Abstract

CdTe microcrystallites were precipitated in 57.8CdO · 19.7SiO2 · 19.0B2O3 · 3.5Al2O3 glasses doped with 5.0 mol % CdTe. The microcrystallite size increased linearly with t1/3 (t: heat-treatment time), indicating diffusion-controlled growth mechanism, where the estimated activation energy for diffusion was 542 kJ/mol. The linear increase in the band gap energy with l/r2 (r: the crystallite radius) suggested the quantum size effect of the CdTe microcrystallites.
