Summary: In this study, LiTaO3:Pr3+,Gd3+ phosphors were synthesized and characterized for their photoluminescence, mechanoluminescence, and thermoluminescence properties. The mechanoluminescence intensity was greatly enhanced by co-doping with Gd3+ ions at an optimal concentration of 1 mol%. The enhanced mechanoluminescence was attributed to the regulated trap quantities and depths caused by co-doped Gd3+ ions, leading to improved optical storage properties.

Summary: This study successfully developed a multi-mode dynamic luminescent material LiGaO2, and different luminescence properties were obtained by adjusting the synthetic atmospheres. The dynamic optical information readout based on intensity-color-wavelength multiplexing in undoped single ODS materials is realized through the synergistic effect of trap centers and luminescence centers.

Summary: In this study, a Y3Al2Ga3O12:Pr3+,Eu3+ optical storage phosphor with Pr3+ as an electron donor and Eu3+ as an electron trap is designed, and a single wavelength write-read scheme is demonstrated using a blue laser diode (LD) light source. The deep electron trap with a mean depth of 1.42 eV and a narrow distribution of 0.3 eV shows the potential for long-term storage. These findings will advance the electron trapping optical storage scheme.

Summary: UV-charged optical stimulated single-band phosphors are commonly used for single-level optical data storage. However, UV-visible-NIR rechargeable optical stimulated double-band phosphors are urgently needed for multiplexed high-throughput optical data storage. In this study, the authors designed and synthesized a Mn2+,Cr3+ co-doped zinc gallate phosphor that exhibits strong red-green bicolor persistent luminescence (PersL) and can be charged by visible and NIR light. The temperature-dependent intensity of red and green PersL, along with the mechanism based on different trap types and filling approaches, are proposed. This phosphor shows great potential for wavelength multiplexing in optical data storage.

Summary: This study reports a novel ortho-silicate phosphor, BaCaSiO4:Eu2+, with sustained luminescence and optically stimulated luminescence (OSL) properties. The long afterglow and OSL performance of BaCaSiO4:Eu2+ significantly improved with the co-doping of Pr3+, leading to a substantial increase in trap density. The optical storage capacity of the OSL material significantly increased due to numerous trapped and released electrons. The OSL-based ODS mechanism was revealed through a comprehensive study of electron trapping, storage, and release kinetics.

Summary: A new material, YBO3:Pr3+, was reported, which can emit intense and long-lasting ultraviolet-C (UVC) persistent luminescence in a bright indoor lighting or outdoor sunlight environment after ceasing X-ray excitation. The UVC persistent luminescence is free from the interference of the ambient light due to the continuous and efficient photostimulation of polychromatic ambient light. This finding not only lays the foundation for developing more UVC persistent phosphors suitable for working in a bright environment, but also promotes the widespread use of these storage phosphors across various applications.

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.
