The relationship between fading rate and the microstruoture of the glasses was investigated by TEM. The results suggest that those glasses with fine and uniform immissible droplets give fast fading rate, whereas for those glasses having slow fading rate the alkali-boron-rich phase area is obvioursly larger and AgX droplets are aggregated.展开更多
