Sol-gel Preparation Copper-cadmium Halide DopedPhotochromic Glass Coating on Plate Glass

摘要

Copper-cadmium halide doped photochromic glass coating on plate glass has been prepared by a sol-gel process. The sample shows reversible photochromic effect. The results of X-ray diffraction （XRD） and infrared （IR） spectrum investigations indicate that the photochromic phase of tile coating is CuBrxCl1-x, solid solution, and that the structure network of the coating is connected with the bonds of Si-O-Si, Si-O-B and Si-O-Al.
