| Abstract: | The sulphides of
cadmium and zinc are widely used materials due to their suitable energy band
gaps. Their energy band gap depends on the particle size. The materials have
been prepared using a simple solution of CdCl2 and ZnCl2
mixed in proper ratio without use of thiophenol. Precipitate of CdZnS is
obtained by passing H2S, liberated from heated thiourea through this
solution. It is confirmed by X-ray diffraction (XRD) and optical band gap
estimation that materials prepared are nano-materials. The optical band gap of
these materials has been determined in order to establish a relationship
between energy band gap of bulk and nanomaterial. It has been noticed that
optical band increases with the increase of Zn concentration in CdZnS. |
