Abstract

We report the results of structural and optical studies of semiconductor microparticle composites consisting of small CdSe crystallites embedded in a silicate glass matrix. Raman scattering and x-ray diffraction studies indicate that the microparticles in the present studies are pure CdSe crystallites with a diameter of 6 nm. We outline the analysis of room-temperature optical absorption and photoluminescence data to deduce the particle-size distribution when the band edge is controlled by quantum confinement.
