Dear Editor, Tungsten-based photochromic materials are well known,such as tungsten-phosphate glasses,tungsten-tellurite glasses,and tungsten-borate glas-ses1.Photoluminescence glasses exhibit a wide range of application in the fields of display,lighting,laser and optical thermometry,et al.Combination of photo-chromic 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 reac-tion,especially achieved the real complex three-dimensional patterns using laser directly writing tech-nology 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.
