Abstract:
Thin films (MPAMI) doping by copper oxide (CuO) (10%) were prepared on glass bases using the Pulsed Laser Deposition (PLD) technique. The effect of the doping ratio on laser pulses (1000, 3000, 5000) mj/cm2 on the optical properties for these thin films was examined. The energy gap values ??were shown to decrease by increasing the laser pulse energy to reach 2.2eV for the nanofilm with a pulse about of 5000 mJ/cm2. While the permeability property was improved in contrast to the absorbance effect. This improvement is benefited according to application. While photoluminescence is decreased and shift it to blue (towards blue) so that the peaks are low and with an extended plateau and between decreasing reflectivity intensity to increase wavelength in an oscillating manner as well as increase the energy of laser pulses, decreasing intensity but led to the displacement of the peak of the reflectivity spectrum to blue displacement, and can be observed decrease of acute refractive index values ??at the beginning of the measurement and at the wavelength (320 nm). The behavior of the extinction factor curves is may be an explanation of the waning radiation within the material by two mechanisms, the first being the absorption, and the second the amount of the scattering that is forward or background.
