Description
Summary:	The Addition of impurities and the nature of substrate are known to change the properties of any deposited thin films. In this work, the influence of doping on the structural and optical properties of PdS thin films grown by chemical bath method has been studied. Aluminum (Al) was used as the dopant for PdS thin films deposited at room temperature. Band gap energy (E g), and other optical parameters were determined from the optical transmission of the film. The estimated energy band gap for the films varied from 1.50 to 1.80 eV. Nanocrystal PdS thin films exhibited a tetragonal structure with average crystallite size of 60 nm. The results obtained prove that doping has profound and superficial effects on optical and structural properties of the deposited PdS thin films.
