【Abstract】 Adding high valence oxide to ordinary photochromic glass can increase the refractive index of the glass.As a result the photochromic glasses whose refractive index is over 160 have been manufactured.The experiment indicates that high valence oxide affects the photochromic properties besides increasing the refractive index.At the same time,the impacts of thermal treatment temperature and thermal treatment time on photochromic properties are discussed.The results show that the photochromic properties became worse with the augment of high valence oxide; the impact of thermal treatment temperature on high refractive index and photochromic glass is more prominent compared with that of ordinary photochromic glass; and the saturated transmittances are different in different thermal treatment time.更多还原
