| Abstract | ||
| In the present study, ZnO thin film have been prepared on glass substances using chemical spray pyrolysis with thickness 1000 Ao laser Nd-YAG irradiation (weavlength 532 nM) and energy (300mW) for 10s from 50cm distance. Optical properties ( energy gap, absorption coefficient, extinction coefficient) have been studied. The results show that laser irradiation cause reduce in energy gap from (3.04)eV to (2.88)eV. | ||
