Abstract :
A thin film is a layer of material ranging from fractions of a nanometer to
several micrometers in thickness. The controlled production of materials
as thin films is a crucial step in many applications. In this work, CdS
thin films were prepared by spray pyrolysis procedure at temperature 450
oC. The XRD, AFM and UV-Visible analysis were utilized to investigate
the CdS films. The XRD investigation showed that prepared thin films
have hexagonal structure with a particular direction along (101) plane. The
crystallite size was measured from X-ray diffraction utilizing Scherrer's
equation. Atomic force microscopy (AFM) confirmed that the grain was
consistently disseminated over the outside of the substrate for the CdS
films. The grain size of the nanoparticles were calculated 66.26, 57.11 and
56.52 nm for the CdS, CdS :2% Cu, CdS :4% Cu respectively. The optical
properties were done utilizing the UV-Visible analysis. It is found that Cu
content affect the optical properties and via increasing the Cu amount, the
band gap was decreased.
