As for the results of the optical properties, it noted that the value of absorbance increases with increasing molar concentration at the point of absorption in the wavelength (320nm) before and after annealing, the results of the Photoluminescence (PL) examination Approached the visible when the violet color before annealing, after annealing, it approached more to the ultraviolet area, as well as the intensity increased, but when the concentration increased, we get the excitement of higher intensity and it was found that the band gap increases with increasing concentration (3.52- 3.70)eV and also increases after annealing (3.60 – 3.76)eV. The Laser (PSU-H-FDA) with a wavelength (473nm) and pulse laser device of the type (Fiber Laser-1064nm-100W), the input power (130 mW),(34W) respectively for all thin films it was found that the highest attenuation of laser radiation was at the higher concentration(0.1mol/L) the lower the Power transmittance(25mW) and (11W) as well as after annealing.
