To membranes prepared CuO impurity effect of fluorine on the optical constants Thermochemical decomposition in a way

Abstract

In this research, the study of effect of doping CuO by F with ratios 1%%3 , %5, on the optical properties of thin films , this thin films have been prepared on a preheated glass substrates upto 425oC using chemical spray pyrolysis technique .the as deposited thin films were studies about . Absorptance and transmittance spectra were recorded in the wavelengths range (300-1200) nm. the optical parameters such as reflectivity, absorption coefficient , extinction coefficient, refractive index , real and imaginary parts of dielectric constant were all studies
