Abstract

It is shown experimentally that subnanodimensional molecular clusters (CdS)n are formed by synthesis in fluorophosphate glass containing cadmium and sulfur ions. They possess an intense luminescence in the visible region of the spectrum when being excited by UV radiation. Thermal treatment of such glass results in an increase in the size of the molecular clusters and makes their optical properties approach those of semiconductor CdS quantum dots. Luminescent fluorophosphate glass with (CdS)n clusters can find applications in spectral down-converters of solar UV radiation in solar energetics, in light-emitting diodes of white radiation, and in luminescent detectors and sensors.
