The launch of the big data era puts forward challenges for information preservation technology, both in storage capacity and security. Herein, a brand new optical storage medium, transparent glass ceramic (TGC) embedded with photostimulated LiGa₅O₈: Mn²⁺ nanocrystals, capable of achieving bit-by-bit optical data write-in and read-out in a photon trapping/detrapping mode, is developed. The highly ordered nanostructure enables light–matter interaction with high encoding/decoding resolution and low bit error rate. Importantly, going beyond traditional 2D optical storage, the high transparency of the studied bulk medium makes 3D volumetric optical data storage (ODS) possible, which brings about the merits of expanded storage capacity and improved information security. Demonstration application confirmed the erasable–rewritable 3D storage of binary data and display items in TGC with intensity/wavelength multiplexing. The present work highlights a great leap in photostimulated material for ODS application and hopefully stimulates the development of new multi-dimensional ODS media.

大数据时代的开始，在存储容量和安全性方面都对信息保存技术提出了挑战。本文中，一种全新的光学存储介质，透明玻璃陶瓷（TGC）嵌入了受光刺激的LiGa ₅ O ₈：Mn ²⁺开发了能够以光子俘获/去俘获模式实现逐位光学数据写入和读出的纳米晶体。高度有序的纳米结构使光与物质之间的相互作用具有较高的编码/解码分辨率和较低的误码率。重要的是，超越传统的2D光学存储，所研究的大容量介质的高度透明性使3D体积光学数据存储（ODS）成为可能，这带来了扩展存储容量和提高信息安全性的优点。演示应用程序证实了具有强度/波长多路复用的二进制数据的可擦写3D存储和显示在TGC中的项目。目前的工作突出了光刺激材料在ODS应用中的巨大飞跃，并有望刺激新的多维ODS介质的发展。
