| Abstract | ||
| In this research, thin films of ZnO of thickness 5200ű30 prepared using chemical spray method. The films deposited on Crown glass substrates Optical studies show that in these films the electronic transition is of the direct transition type. The optical energy gap for the films of as deposited and for those heat treated for an hour at different temperatures is estimated to be in the range 3.05-3.2 eV. Results analysis exhibits the dependence of optical energy gap on the temperature of heat treatment. | ||
