Silicate glasses containing CdS and Ag2O were made by the melt-quenching method. CdS quantum dots (QDs) were precipitated inside the glass matrix by heat treatment at 570-590 degrees C for 10 h, and the influence of Ag on photoluminescence (PL) of CdS QDs was investigated. The emission located at 478-493 nm in wavelength originated from the direct recombination of electron/hole pairs was quenched due to charger transfer between Ag and CdS QDs. Modification of PL from CdS QDs by Ag provides potentials toward developing the color changing materials for light-emitting diodes (LEDs).
