All-inorganic CsPbBr3 perovskite nanocrystals (NCs) have stimulated the enthusiasm of the research on light emitting diodes (LEDs), laser, X-ray detection, and information encryption, thanks to their excellent optical performance. Exploiting CsPbBr3 NCs with fascinating long persistent luminescence (LPL) is significantly important for expanding their potential applications. In this work, the room temperature LPL is successfully achieved in CsPbBr3 glass-ceramics (GCs) through the optical write with a femtosecond (fs) laser. The carriers captured by the generated trapping centers for the crack of non-bridged oxygen bonds in the glassy matrix are released by the thermal disturbance of room temperature. Moreover, the LPL performance is modulated flexibly for doping with La3+, Dy3+, Nd3+, and Lu3+ ions in the CsPbBr3 GCs, endowing the successful construction of a time-resolved anti-counterfeiting mode. Furthermore, the high stability and high color purity (97.04%) of the as-obtained CsPbBr3 GCs are demonstrated. The results open a window for fs laser induced perovskite with myriad applications in optical storage devices.

玻璃中 CsPbBr3 纳米晶体的上转换长余辉发光
全无机CsPbBr 3钙钛矿纳米晶(NCs)以其优异的光学性能激发了发光二极管(LED)、激光、X射线检测和信息加密等领域的研究热情。利用具有迷人长余辉发光 (LPL) 的CsPbBr 3 NC 对于扩展其潜在应用非常重要。在这项工作中，室温 LPL 在 CsPbBr 3中成功实现通过使用飞秒 (fs) 激光进行光学写入的玻璃陶瓷 (GC)。玻璃基体中非桥氧键裂纹产生的俘获中心俘获的载流子在室温热扰动下释放。此外，在CsPbBr 3 GCs中掺杂La 3+、Dy 3+、Nd 3+和Lu 3+离子可灵活调节LPL性能，成功构建时间分辨防伪模式。此外，所获得的 CsPbBr 3 GC 具有高稳定性和高色纯度 (97.04%)。结果为 fs 激光诱导钙钛矿打开了一扇窗，在光存储设备中有无数的应用。
