Abstract

CdTe microcrystallites were precipitated in 57.8CdO 19.OB2O3 3.5A1203 glasses doped with 5.0 mol % CdTe. The microcrystallite size increased linearly with tm (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 1/r²(r: the crystallite radius) suggested the quantum size effect of the CdTe microcrystallites.
