Summary: This paper reports on the luminescence and thermometric properties of Ca4(PO4)2O:Eu. The emission of Eu2+ showed blue and red bands, while Eu3+ exhibited yellow and red lines. The thermometric properties in different spectral ranges were studied using the luminescence intensity ratio method. Average temperature sensitivities of 1.76%, 0.1%, 0.11%, and 0.11%/°C were obtained in the blue-green, yellow, red, and near-infrared spectral ranges, respectively. The material could be potentially used in low-temperature thermal imaging applications.

Summary: Zinc titanate phosphors with Eu3+/Mn4+ as active ions were synthesized. XRD patterns confirmed a mixture of cubic Zn2TiO4 and hexagonal ZnTiO3 phases. The luminous intensity of ZTO: Eu3+ and ZTO: Mn4+ phosphors increased with doping concentration, reaching maximum values at 2 mol% Eu3+ and 0.3 mol% Mn4+, respectively. Photoluminescence spectra revealed characteristic peaks of Eu3+ at low Mn4+ content, and both Mn4+ and Eu3+ luminescence peaks at higher Mn4+ content. The relative sensitivity of the samples in variable temperature spectra improved with increasing Mn4+ concentration, reaching a maximum value of 3.2 %/K.

Summary: Fluorescence temperature measurement technology has sparked a new wave of non-contact temperature measurement, but the single-mode thermometry still has a large error. In this study, a dual-mode modulation thermometry based on GaNbO4:Yb3+/Er3+ up-conversion phosphor is achieved in a wide temperature range of 93-633 K, with a maximum relative sensitivity of 11.7% K-1 (93 K) and 13.1% K-1 (123 K). The GaNbO4:Yb3+/Er3+ phosphors were synthesized using the high temperature solid-state method and characterized for their structure, surface morphology, and optical properties. The fluorescence intensity ratio (FIR) readout method based on Er3+ thermal-coupled and non-thermal-coupled energy levels was used for the dual-mode temperature measurement. The results demonstrate the great potential of GaNbO4:Yb3+/Er3+ phosphors in high sensitivity broadband thermometry.

Summary: This work proposes a ratiometric dual-emitting mechanoluminescence (ML) strategy to achieve stress-sensitive ML color variation. The combination of Lanthanide/transition-metal is used to construct the dual-activator ML system. The difference in electronic configuration between Lanthanide and transition-metal ions plays a key role in the response of corresponding luminescence kinetics to stress-induced local crystal field environment changes.

Summary: The size-dependence of thermally enhanced upconversion luminescence (UCL) for UCNPs has been previously considered to be monotonous. However, this study finds that the monotonic relationship between UCL thermo-enhancement ratio and particle size is broken when the size of UCNPs goes below 7 nm. The breaking of monotonicity is accompanied by a change in the relationship between luminescence properties and particle size and supports the explanation of UCL thermo-enhancement through lattice thermal expansion-induced alleviation of surface quenching.

Summary: This paper reports a new type of mechanoluminescent phosphor, Ca5Ga6O14:Tb3+, which exhibits trap-independent, self-recoverable mechanoluminescence and a low mechanical stimulus threshold. Experimental and theoretical studies reveal that the mechanoluminescence is attributed to the piezoelectricity resulting from the non-centrosymmetric mm2 point group of the Ca5Ga6O14 host. The phosphor possesses giant piezoelectric coefficients, comparable to or even higher than many commonly used piezoelectric materials, making it suitable for battery-free, energy-saving piezo-photonic applications.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
