Summary: The emission and visible photoluminescence excitation spectra of Y2O2S:Er (1 at %) ceramics were investigated. The results showed that the visible anti-Stokes luminescence of the erbium-doped material exhibited higher intensity when pumped with the I-4(13/2) metastable state. The study also developed an optical excitation method for the metastable states in anti-Stokes luminescence.

Summary: In this study, an Er3+-doped AlN film was prepared and characterized for its photoluminescence properties. The film exhibited emissions in both visible and near-infrared ranges. Energy transfer between Er3+ and AlN defect-related transitions was observed, leading to enhanced luminescence efficiency of Er3+.

Summary: Microcrystalline anti-Stokes luminophores NaY1-x-y-zYbxEryLuzF4 were successfully obtained for the first time via hydrothermal synthesis. These compounds crystallize in the hexagonal crystal system, with the structural type beta-NaYF4. Addition of non-luminescent lutetium(III) ions was found to result in more than 2 times enhancement in up-conversion luminescence upon 980 nm excitation.

Summary: Luminescence thermometry is a powerful technique that allows for non-invasive temperature monitoring through light. This study presents the use of isolated single up-converting NaYF4:Er3+/Yb3+ nanocrystals as functional temperature indicators for monitoring the temperature of a single silver nanowire. The results demonstrate the precise determination of temperature distribution in the nanowire's surroundings using individual nanocrystals, which is an important step for nanoscale luminescence thermometry applications.

Summary: A high-efficiency and thermally stable broadband near-infrared (NIR) emission was realized in LiSrGaF6:Cr3+ fluoride phosphor, which exhibited ultra-broad NIR luminescence ranging from 650 to 1150 nm under blue light excitation. The pc-LED constructed with this phosphor demonstrated a higher color reproduction and luminous efficiency, making it a promising candidate for high-quality sunlight-like full-spectrum lighting and infrared night vision.

Summary: In this study, a white light emitting hydrogel with multi-stimuli responsive properties was prepared by doping Eu3+ and Tb3+ into a blue emission low molecular weight gelator. The hydrogel showed excellent responsiveness to pH, temperature, and chemicals, and could be used for temperature sensing and Cu2+ detection. It could also be used to construct soft materials of a full-color system and anti-counterfeiting materials. This study provides a new approach for preparing smart white light emitting hydrogels with multiple functions.

Summary: The development of silicon-based radiative nanostructures is a crucial step for silicon-based optoelectronic systems. This study demonstrates a method for fabricating photoluminescent Er-doped silicon nanoantennas. By combining electron beam lithography and laser annealing, an active dielectric nanoantenna operating in the standard telecommunication wavelength range is created. The presence of Mie-resonances enhances the photoluminescence intensity by up to 40% compared to the non-resonant case.

Summary: X-ray induced reduction Ho3+ -> Ho2+ was observed in polycrystalline samples of NaMgF3:Ho. Excitation bands arising from 4f11 -> 4f10(5IJ)5d1 transitions of Ho2+ were observed in the visible spectral region, and a corresponding 4f11(4I13/2) -> 4f11(4I15/2) emission was observed in the infrared at 1808 nm. The reversible Ho2+ <-> Ho3+ conversion may have applications in radiation sensing and optical data storage.

Summary: Yb3+/Nd3+ co-doped CaTiO3 microcrystals were synthesized and showed anti-Stokes emissions in the near-infrared range under 980 nm excitation, which increased with temperature. An optical ratiometric thermometer based on the energy level transitions of Nd3+ ions was constructed, with a high sensitivity of 1.52 % K^(-1).

Summary: In this study, erbium-and ytterbium-containing mesoporous bioactive glass microspheres (MBGs: Er/Yb) with blue and red emission at an excitation wavelength of 980 nm were synthesized. The optimal molar ratio of Er3+/Yb3+ was determined to be 4:3 based on in vitro bioactivity tests. MBGs:4Er/3Yb showed potential applications in biomineralization and drug release monitoring.

Summary: Recently, rare-earth (RE)-free ions (Mn4+) activated phosphor materials, such as double perovskite-type Ba2YSbO6 (BYSO:Mn4+), have gained attention as an alternative source for multi-functional applications. In this study, novel RE-free Mn4+ activated BYSO phosphor materials were prepared using a solid-state reaction method. The BYSO:8Mn4+ phosphors exhibited broad far-red emission under 353 nm excitation, with a maximum intensity at 694 nm, making it beneficial for plant growth.
