| Abstract Scope |
To satisfy the demand for further data growth and low energy consumption storage, the exploration of new optical data storage (ODS) recording materials has drawn intensive attention. Persistent and optically stimulated luminescence materials can find many advanced applications in ODS. However, the lack of suitable materials with deep-level traps is still the bottleneck of such applications. Here we have explored cation substitution and co-doping strategies to tune the optical properties, and ultimately trap engineering, of metal oxide-based phosphors. We are able to tailor their trap depth, density and distribution, which could be used to improve the performance of optical information storage. Our work indicates that trap engineering is an effective way to tune these luminescence properties of our phosphor for optical data storage. Moreover, we have demonstrated the synergistic stimulation of our phosphors as multimode storage media for ODS applications. |
