Structural and Optical Properties of Nanocrystalline Pb1-xCdxS Thin Films Prepared by Chemical Bath Deposition

Abstract

Morphological, structural, optical and electric properties of metal oxide (ZnO) can be tailored through doping of either anion or cation. The doped ZnO thin films and/or powder could possibly increase the photocatalytic properties of ZnO provided that it is being doped preferably either to have p-states near the valence band similar to other deep donor levels in the semiconductor or decreased band gap to realise its catalytic potential under solar irradiations. This could be attained by paying special attentions to the type of dopant (anion or cation), preparation protocols and its extent or concentration in doped ZnO thin films/powder.
