| dc.description.abstract | Cadmium sulfide (CdS) thin films of nanostructure were prepared with Cd:S (1.2 to 0.05
mol/L) and different spin coating speed (1000 and 5000 rpm) using sol-gel spin coating technique.
Structural, morphological and analytical studies were investigated by x-ray diffraction XRD,
scanning electron microscopy (SEM), fourier transform infrared (FTIR) and UV-VIS
Spectrophotometer. It is found that the average grain size of CdS in the thin films is 1.35 to 2.66 nm
for 1000 and 5000 rpm. The band gap was also calculated from the equation relating absorption
coefficient to wavelength. The band gap indicates the film is transmitting within the visible range
and the band gaps changes because of the grain size of the CdS in the films. The physical
conditions were kept identically while growing all the samples. The effect of grain size on the
semiconductor properties is under consideration | en_US |
