Optical Responsive Nanomaterials
In article number 2208561, Zhang, Zheng, and co‐workers report that a self‐encrypted all‐optical memory with ultrahigh switching contrast is realized in Y2O3:Eu3+‐Au. All‐optical information revisable writing, reading, encryption and re‐writing are realized by a change of light power. This study not only provides insight into the unique thermal response of the plasmon...
All‐optical responsive nanomaterials, which can rapidly switch between two stable states, have been regarded as the next‐generation memories due to their potential to realize binary information storage and implement on‐chip, integrated photonic neuromorphic systems. Rare earth oxides are preeminent candidates owing to their extraordinary luminescent stability and narrow optical transitions. However,...
