Non-volatile and Secure Optical Storage Medium with Multilevel Information Encryption.

ABSTRACT: Non-volatile photomemory based on photomodulated luminescent materials offers unique advantages over voltage-driven memory, including low residual crosstalk and high storage speed. However, conventional materials have thus far been volatile and insecure for data storage because of low trap depth and single-level storage channels. Therefore, the development of a novel non-volatile multilevel storage medium for data encryption remains a challenge. Herein, a robust, non-volatile, multilevel optical storage medium is reported, based on a photomodulated Ba₃MgSi₂O₈:Eu³⁺, which combined the merits of light-induced valence (Eu³⁺ → Eu²⁺) and photochromic phenomena using optical stimulation effects, accompanied by larger luminescent a
