Powders and thin films of photochromic glasses containing AgBr or AgCl microcrystals were synthesized via the sol-gel process. Up to 10wt% of Ag+, bonded with suitable complexing agents, were introduced into the matrix system consisting of xSi02-(1-x)Al203(x=0.7...1). After drying and heat treatment, the AgX microcrystals (X=Cl,Br) were characterized by X-ray diffraction and high-resolution TEM. The photochromic properties were measured using a diode array UV-VIS spectrometer.
