摘要

Optical quality PMMA thin film layers including different concentrations of 3nm CdSe/ZnS and 5 nm TiO₂ semiconductor quantum dots have been made by spin coating method. Their optical properties show evident consequences of the confinement effects with wavelength bandgap shifting for both types of QDs. The confinement effects are more pronounced for CdSe/ZnS QDs than for TiO ₂ QDs. Layers including CdSe/ZnS QDs exhibit a strong luminescent behavior centred on 560nm with a stock-shift in front of the first exciton absorption peak.
