Abstract

In this work, Ag2S-CdS hybrid composite with novel luminescence property was synthesized using a one pot and rapid microwave method. Structural analysis by means of XRD and TEM obtained the formation of the composite. Optical spectroscopy by means of UV-Vis and Photoluminescence measurements revealed that the functional composite has an intensive red light emission at 657 nm with a large stocks shift of about 150 nm. The quantum efficiency of the prepared hybrid material in red region is 10% which is comparable with the efficiency of pure CdS (11%) with green emission.
