Reply to Comment on"Reversible 3D optical data storage and information encryption in photomodulated transparent glass medium

Dear Editor,Tungsten-based photochromic materials are well known,suchastungsten-phosphateglasses,tungsten-telluriteglasses,andtungsten-borateglasses'.Photoluminescence glasses exhibit a wide range of application in the fields of display,lighting,laser and optical thermometry,et al.Combination of photochromic and luminescence can extend the application of luminescence materials2-7.Our focus is not on the development of new photochromic materials,but on the control of luminescence through photochromic reaction,especially achieved the real complex threedimensional patterns using laser directly writing technology in photo-modulated transparent glass.In our work2,the three-dimensional optical data storage and information encryption application of photochromic glass with luminescence was obtained.
