Summary: Glasses with tunable properties are versatile materials for optical technologies. To design new optical glasses, understanding the correlation between their chemical composition and physical properties is crucial. We demonstrate the feasibility of using fluoride phosphate glasses co-doped with Pr3+ and Yb3+ ions for temperature sensing. These glasses have high stability and act as luminescent thermometers without the need for recurring calibration. They exhibit competitive thermal sensitivity and uncertainty, making them promising for cost-effective and accurate temperature probes, advancing photonic technologies.

Summary: We propose a computational imaging technique to expand the field of view of infrared thermometers. The contradiction between the field of view and focal length has been a major problem in infrared optical systems. Expensive and technically challenging large-area infrared detectors limit the performance of these systems. However, the increased demand for infrared optical systems during COVID-19 necessitates improving their performance and increasing the utilization of infrared detectors. This study presents a multi-channel frequency-domain compression imaging method based on point spread function (PSF) engineering that reduces the optical system's volume and improves energy efficiency.

Summary: This study overcomes the sensitivity limit of Boltzmann's thermometers by utilizing seven thermalized Dy3+ excited states in the Lu1.5Y1.5Al5O12 host. By extending the conventional two-thermalized level Boltzmann-type luminescence intensity ratio (LIR) to seven thermalized levels, the approach provides higher energy differences and enables a five times larger sensitivity than the conventional LIR.

Summary: We studied the galactic winds in 46 late-stage galaxy mergers of the HizEA galaxies with various properties. Outflows were observed in 90% of the targets with maximum velocities ranging from 550-3200 km/s. Our analysis found strong correlations between outflow velocity, star formation rate, star formation surface density, and weaker correlations with stellar mass and SFR/M-* ratio. These results suggest that the extreme star formation conditions in the HizEA galaxies are responsible for the exceptional outflow velocities.

Summary: The one-point method (OPM) is a convenient way to estimate the maximum apparent carboxylation rate of Rubisco (V'(cmax)) based on a single measurement of leaf carbon assimilation rate under saturating light and ambient CO2 (De Kauwe et al., 2016). However, the OPM overestimates V'(cmax) at high temperatures (Burnett et al., 2019) due to the fixed R-day:V-cmax ratio it assumes, which does not account for different temperature dependencies of these parameters. It is important to adopt a temperature-dependent scaling factor for the R-day:V-cmax ratio to avoid overestimation of photosynthetic capacity at temperatures >35 degrees C.

Summary: Thermocurrent flowing through a single-molecule device provides valuable information about its quantum properties, electronic and phononic excitation spectra, and entropy. Experimentally measuring the thermoelectric heat-to-charge conversion efficiency can help select suitable molecules for highly efficient energy conversion devices predicted by theoretical studies. A superconductor-normal metal-superconductor Josephson junction thermometer is incorporated into the single-molecule device to accurately determine the temperature bias. This device architecture enables precise thermoelectric experiments on individual molecules at millikelvin temperatures.

Summary: Narrower band red and green emission in phosphor-converted white light-emitting diodes can be achieved by using Mn2+ as a luminescent ion. The luminescence quenching temperature of Mn2+ is shown to vary greatly depending on the host material, with a positive correlation with the bandgap of the host. The quenching mechanism is found to be thermally activated photoionization, and a wide-bandgap host material is required for temperature-stable Mn2+ luminescence in high power LEDs.

Summary: The synthesis of beta-NaYF4 nanocrystals from alpha-NaYF4 precursor particles was investigated using in situ small-angle and wide-angle X-ray scattering and ex situ electron microscopy. It was observed that the particle size distribution evolved from unimodal to bimodal, and eventually back to unimodal, with the final distribution being narrower than the initial distribution. The splitting of the size distribution was attributed to variations in the reactivity of the precursor particles.

Summary: A new biocompatible thermometer CaGa4O7:0.01 % Mn2+, 0.05 % Cr3+ is proposed in this study to overcome the limitation of luminescence thermal quenching in high-resolution luminescent thermometers above 400 K. The thermal enhancement of Mn2+-based emission enables a high signal-to-noise ratio at temperatures above 520 K, making it suitable for ratiometric temperature readout and thermal imaging.

Summary: Based on simple optical spectroscopy, this study identifies the reversible charge transfer mechanism in the benchmark persistent phosphors CaAl2O4:Eu2+,Nd3+. The forward charge transfer from Eu2+ to Nd3+ and the backward charge transfer from Nd2+ to Eu3+ are confirmed. The percentages of Eu2+ and Nd3+ involved in the charge transfer exceed previous estimates in other persistent phosphors, and this strategy also offers additional advantages of site selectivity in identifying different contributions of Nd3+ sites. These findings highlight the importance of reversible charge transfer in persistent phosphors and contribute to a better understanding of the persistent luminescence mechanism.

Summary: Mn4+-doped fluorides are commonly used phosphors for warm-white lighting by converting blue light from LEDs into red light. However, they suffer from droop, i.e., decreasing performance at higher power, which limits their application in high-power scenarios. This study provides a comprehensive explanation of droop in Mn4+-doped K2TiF6 by considering all previously proposed mechanisms. By combining experimental and modeling approaches, the contributions of absorption bleach, thermal quenching, and Auger quenching at different excitation densities are quantified. This work contributes to a better understanding of the limitations of these materials and may inspire strategies to enhance their efficiency in high-power applications.

Summary: The impact of the surrounding ligand field is successfully used to tune the emission characteristics of Eu2+ in inorganic photoactive materials, but the underestimated influence of local ligand field effects on the photoluminescence of Mn2+ is explored in this study. The concept of electronically tuning the emission color of transition metal ions in inorganic hosts is demonstrated for the Mn2+-containing solid solutions Zn1-xMnx[B-2(SO4)(4)]. By analyzing the electronic Racah repulsion parameters, it is shown that Mn2+ can be a potent alternative emitter to Eu2+ for inorganic phosphors by electronically controlling the metal-ligand bond.

Summary: The anionic diamido N-heterocyclic carbene 1 is used to synthesize a variety of Cu(I) complexes with small molecular ligands. Key to the synthesis is a stable coordination polymer [1 center dot Cu](n) that can be easily converted into monomeric complexes by adding desired ligands. Spectroscopic experiments are limited to the crystalline state of the complexes, which exhibit visible luminescence in the solid state. Quantum mechanical computations reveal the role of coordination number and charge transfer character in the spectral features of the complexes.

Summary: This study presents and compares the photoluminescence properties of compounds mBN, BPN, and pBN. While pBN exhibits thermally activated delayed fluorescence (TADF) properties, mBN shows weak TADF and BPN functions as a conventional fluorescent emitter. The through-space overlap between phenazinediyl and benzonitrile units is found to be effective only in pBN. The emission of these compounds in solution is weak, with the strongest intensity observed in toluene.

Summary: This study analyzes the impact of excitation and detection geometry, as well as sample thickness, on the spectroscopic properties and performance of luminescent thermometers. It finds that thick-layer samples exhibit significant changes in luminescence intensity ratios compared to thin-layer samples, resulting in different absolute and relative sensitivities for different sample thicknesses. These changes are attributed to a reabsorption effect, particularly pronounced in the transmission (back-illuminated) geometry of thick-layer samples. The results of this study have important implications for the accuracy of optical temperature monitoring using Er3+ ions.

Summary: The photoluminescence of lanthanide-doped nanocrystals can be quenched by energy transfer to nearby molecular vibrations, which is often undesired but can provide information about molecular vibrations in the local environment. This study investigates the influence of solvent and gas environments on the photoluminescence properties of NaYF4:Er3+,Yb3+ upconversion nanocrystals and relates the changes to quenching by electronic-to-vibrational energy transfer. The results suggest that EVET-mediated quenching can be used as a mechanism to probe the local chemical environment in liquid and gas-phase systems.
