Summary: The highly sensitive afterglow intensity ratio (AIR) thermometry based on thermal quenching (TQ) mechanism using Y3Al2Ga3O12:Pr3+ persistent phosphor is reported. The AIR shows strong temperature dependence in the range of 30-170 degrees C, with a maximum relative sensitivity of up to 4.12% degrees C-1 at 170 degrees C. The method is demonstrated by accurately measuring water temperature with an error of only 0.1 degrees C.

Summary: Introducing smaller Mg2+ ions to replace Ca2+ site in the BaLaCaSbO6 matrix leads to a significant enhancement in luminescence intensity, red-shift, and luminescence lifetime. These modulations are mainly attributed to the strengthen pressure on the local structure, superior lattice rigidity, and suppression of non-radiative transition after the substitution of smaller Mg2+. The effective lifetime-based luminescence thermometry is achieved due to thermal quenching behavior of Mn4+ ions in the matrix.

Summary: A series of SrGa12-xAlxO19:0.5%Cr3+(x = 0, 2, 4, and 6) solid-solution phosphors were successfully synthesized through Al3+ alloying strategy. The introduction of Al3+ can regulate the crystal field and symmetry, achieving the synchronous tuning of E-2 and T-4(2) energy levels and extending the temperature sensing range. Among all samples, SrGa6Al6O19:0.5%Cr3+ showed the widest temperature measuring range from 130 K to 423 K with Sa of 0.0066 K-1 and Sr of 1% K-1@130 K. This work provides a feasible way to extend the temperature sensing range for transition metal-doped LIR-mode thermometers.

Summary: Precisely composition-tuned lanthanide-organic thin films with white light emission are fabricated using ALD/MLD technique. The emission characteristics are comparable to or even better than those of commercial incandescent bulbs, fluorescent tubes, and LED lamps. The films consist of up to four lanthanide species and terephthalate as the organic linker, which not only provides mechanical flexibility and defines the distance between lanthanide ions but also exhibits UV/blue broad-band emission upon UV excitation. The emission energy is efficiently transferred to Er3+ ions, resulting in longer wavelength emission, while Tb and Eu contribute to green and red emissions, producing warm white light emission in the films. By controlling the distribution of Ln dopants using a three-layer composition, the emission intensity is increased fourfold.

Summary: In this paper, we present a versatile method that allows the preparation of triboluminescent polymer films by physically blending them with common luminophores. The method does not require a crystalline phase or materials known to be triboluminescent. The emission is generated through triboelectrification caused by the friction of the polymer surface, either by direct rubbing or through an inert coating layer, even at low applied stress levels (<0.1 MPa). Our findings provide a convenient and practical way to prepare amorphous triboluminescent polymer films with easily adjustable emission properties.

Summary: Rare-earth doped nanoparticles (RENPs) have attracted increasing interest in materials science due to their optical, magnetic, and chemical properties. RENPs can emit and absorb radiation in the second biological window (NIR-II, 1000-1400 nm), making them ideal optical probes for in vivo imaging. The optimization of thermal sensitivity in RENPs depends on the core chemical composition and size, active-shell, and outer-inert-shell thicknesses.

Summary: Composition control is a powerful tool for adjusting the optical outputs of high-performance lanthanide luminescent materials. Although commonly used in hierarchically structured nanoparticles, this strategy is seldom applied to molecular compounds due to the limited number of metal centers within a single unit. In this study, we investigate the composition control in a series of molecular cluster-aggregates with an icosanuclear core, aiming to adjust the optical output similarly to nanoparticles. Through exploring the impact of the addition of a third doping ion, we gain insights into the luminescent processes and qualitative trends in each molecular cluster-aggregate.

Summary: Remote temperature probing at cryogenic range is crucial for the advancement of future quantum technologies. In this study, a novel magneto-optical thermometric approach based on magnetic-circular dichroism(MCD) technique is proposed, which offers unprecedented capabilities for meticulous temperature variation analysis at cryogenic temperatures. The use of MCD C-term's temperature sensitivity, combined with both positive and negative signals, enables highly sensitive magneto-optical temperature probing. Additionally, a groundbreaking high relative thermal sensitivity value of 95.3 % K-1 at 2.54 K can be achieved using a mononuclear lanthanide complex, [[Ho(acac)(3)(phen)], in the presence of a 0.25 T applied magnetic field and using a combination of multiparametric thermal read-out with multiple regression. These results unequivocally demonstrate the viability and effectiveness of the proposed methodology for cryogenic temperature sensing.

Summary: In this study, ultra-small gold nanoparticles stabilized by co-ligands were synthesized, and their physicochemical properties were controlled by the amount of reducing agent used. The absorption cross-section was significantly increased by precisely controlling the reducing agent, which in turn influenced the photoluminescence quantum yield. The results suggest that the physicochemical properties of the ligand shell can be tuned to control the near-infrared absorption and photoluminescence of the gold nanoparticles.

Summary: Luminescence nanothermometry is a technique that uses luminescence signals from nanosized materials to remotely and minimally invasively measure temperature. However, in a biomedical context, the reliability of temperature measurement is compromised by bias caused by environmental conditions. This study reveals an unexpected source of bias induced by metal ions, which enhances the emission of Ag2S nanothermometers. These findings highlight the need for caution when using luminescence nanothermometry in complex biological environments.

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.
