如今，光数据存储（ODS）已经成为数字时代最有前途的数据存储技术之一。光激发发光（OSL）材料被认为是新一代ODS的重要候选材料。易失性存储器性能的提高和存储容量的增加是当前需要解决的两个关键问题。本文报道了一种新型的Eu2+掺杂正硅酸盐荧光粉，该荧光粉具有持续发光和光致发光的特性。通过Dy3+共掺杂，捕获密度显著提高了10倍。信息可以通过紫外线照射可逆地写入陷阱，然后通过光学或热刺激读出。详细研究了电子被陷阱捕获和释放的动力学过程，揭示了基于光离子的ODS机制。此外，作为概念验证，利用获得的OSL材料制作了ODS柔性介质，以验证可擦除光学数据写入和读出的应用可行性。
Nowadays, the optical data storage (ODS) has already become one of the most promising data storage technologies in this digital era. Optically stimulated luminescence (OSL) material has recognized as a considerable potential candidate for the new-generation ODS. The improvement of volatile memory performance and the increase of storage capacity are two critical challenges to be solved. In this work which is reporting on, a new novel Eu2+-doped orthosilicate phosphor has been studied showing both persistent luminescence and OSL. The trap density is significantly enhanced by 10-fold via Dy3+codoping. Information can be reversibly written into the traps by UV light illumination and then read out by optical or thermal stimulus. The capture and release dynamics of electrons by traps are studied in detail to reveal the OSL-based ODS mechanism. Moreover, as a proof-of-concept, ODS flexible medium is fabricated using the as-obtained OSL material to certify the application feasibility for erasable optical data write-in and read-out.
