Summary: In this work, a series of Pr3+-doped Y3GaO6 long persistent luminescence (LPL) phosphors were developed, taking advantage of the synergy between the host lattice, emitters, and carrier traps. The phosphors exhibited visible LPL for 6 hours and strong thermoluminescence (TL) spectra even after being stored in darkness for 20 days. Additionally, photostimulated luminescence was observed under low-energy excitation. The proposed mechanism for LPL was supported by investigating the crystal structure and possible defects. The Pr3+-doped YGO LPL phosphors have potential applications in multi-color anticounterfeiting and long-term continuous detection of short-wavelength UV radiation.

Summary: Long persistent luminescence materials are primarily concentrated in the blue and green regions, with few options available in the red region. The development of red persistent phosphors has a broader application potential but remains challenging. A solid-state reaction method was used to synthesize new red persistent luminescent materials, which showed intense red afterglow that lasted more than 1400 s and luminescent thermal stability. These materials have potential applications in anti-counterfeiting due to their time and temperature sensitive output signal.

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: A strategy for achieving full-visible-spectrum lighting in phosphor-converted white light emitting diodes (pc-WLEDs) is explored by engineering the lattice site occupancy. The introduction of Yb3+ into the Sr sites induces lattice disorder, increases the Sr vacancies, and leads to a remarkable blue emission. Furthermore, a high color-rendering index (CRI) of 89.6 and a correlated color temperature (CCT) of 5382 K are demonstrated in a WLED device fabricated with a combination of Sr3Ga4O9: Bi3+, Yb3+ and CaAlSiN3: Eu2+ phosphors.

Summary: In this study, a one-dimensional Cs5Cu3Cl6I2 scintillator with high thermal stability was designed and developed. The scintillator showed high thermal stability due to the bridges formed by I-ions in the 1D chain structure, improving its structural rigidity. It exhibited a high steady-state light yield (59,700 photons MeV-1) and the highest spatial resolution for powder-based scintillation screens (18 lp mm-1) after cyclic treatment within the temperature range of 298-423 K. The Cs5Cu3Cl6I2 scintillator has significant potential for application in high-temperature environments, as it allows the visualization of alloy melting. This study provides a new perspective for the design of scintillators with high thermal stability.

Summary: X-ray time-lapse imaging allows for precise radiographic imaging after X-ray termination, simplifying X-ray detectors and avoiding health hazards. By replacing sodium ions with cesium ions, monodisperse NaLuF4:Tb3+ nanocrystals achieve superior X-ray time-lapse imaging. The incorporation of cesium ions amplifies deep trap storage capacity, ensuring stable carriers even after 192 hours of X-ray termination. X-ray time-lapse imaging not only accurately reads long-term stored imaging information but also visualizes X-ray imaging independent of dangerous radiation, providing great opportunities for large-scale X-ray inspection.

Summary: Direct laser patterning allows precise tailoring of perovskites at the microscale, which is important for advanced optoelectronic devices. However, thermal ablation can lead to imprecise crystallization, limiting the resolution of the technique. This study demonstrates a method of crystallizing perovskite nanoparticles by photon effect, avoiding undesired crystallization and destruction. This technique enables the production of high-transparency, high-resolution, and stable multicolor perovskite PVDF films, potentially applicable in flexible displays.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
