Paper Abstract

Microcrystalline CdTe-doped glasses were prepared by heating the gels in H2-N2 atmosphere. When heated in H2-N2 gas, Te ions were reduced into Te2-, which reacted with Cd2+, ions to form CdTe crystals. The size of CdTe crystals was about 3.5 nm in radius, which was controlled by changing the conditions of gel synthesis. The optical absorption edge energies were reciprocally proportional to the square of the crystal radius.
