摘要：
CdSe thin films were synthesized on the glass substrate by chemical bath deposition technique within the pores of polyvinyl alcohol (PVA) at 60 degrees C. In order to study the effect of the capping polymer on the properties of these films, similar deposit was carried out using water as the deposition medium. The as-deposited films were annealed in the oven at 200 degrees C and characterized for the composition and optical properties. These properties were studied by means of Rutherford backscattering (RBS) and optical spectrophotometer. The optical properties revealed the presence of direct band gaps with energies in the range of 0.9 - 1.2eV (for the films deposited in water medium) and 1.8 - 2.0eV (for the films deposited in PVA medium). The deposition medium has significant influence on other optical and solid-state properties studied.
