主　　题：encryption optical transparent 

摘      要：Transparent glass has been identified as a vital medium for three-dimensional(3D)optical information storage and multi-level ***,it has remained a challenge for directly writing 3D patterning inside a transparent glass using semiconductor blue laser instead of high-cost femtosecond ***,we demonstrate that rare earth ions doped transparent glass can be used as 3D optical information storage and data encryption medium based on their reversible transmittance and photoluminescence *** color of tungsten phosphate glass doped with rare earth ions change reversibly from light yellow to blue upon alternating 473 nm laser illumination and temperature stimulation,resulting in the reversible luminescence *** information data could be repeatedly written and erased in arbitrary 3D space of transparent glass,not only showing the ability of the excellent reproducibility and storage capacity,but also opening opportunities in information *** present work expands the application fields of luminescent glass,and it is conducive to develop a novel 3D data storage and information encryption media.
