Materials study demonstrates trap level modulation in phosphor electronic structures, suggesting a pathway toward secure and high-capacity multidimensional optical data storage.
Driven by booming electronic information technology, massive digital data overloads current storage systems. Limited by optical diffraction, traditional optical media struggle to further boost storage capacity. To address these challenges, Yichun Liu and colleagues recently reported an advanced storage strategy in National Materials . This work embeds intrinsic storage functionality into the electronic structure of phosphor materials, shifting the technical emphasis from hardware sophistication to material endogenous properties. The strategy pioneers a secure, multidimensional, and cost‐effective optical storage paradigm.
