摘　　要：研究了以铜镉卤化物作为光敏剂的无银光致变色玻璃的基本组成φ=(R_2O-Al_2O_3)/B_2O_3与光色性能的关系.并用红外光谱和拉曼光谱研究了玻璃的基本结构.结果表明,基础玻璃是由[SiO_4]、[AlO_4]、[BO_4]、[BO_3]共同组成的空间网络.热处理导致玻璃中各种基团富集而分相,在分相时析出CuX-CdX_2光敏微晶,玻璃具有光色性能.In the paper, the relations between the basic composition φ = (R_2O-Al_2O_3)/B_2O_3 of photochromic Copper-Cadmium halides and the photochromic properties are studied. The basic structure before and after heat-treatment is investigated in terms of IR and Raman Spectroscopy in details. The results demanstrate that the space network of body glass is conatructed by [SiO_4]、[BO_4]、[AIO_4] and [BO_3],Heat-treatment results the phase seperation. At meantime, the tiny crystals of CuX-CdX_2 are seperated out which result the photochromic phenomenon.
