Synthesis of thin films and Study of the Change in Some of Their Optical and Electrical Properties Due to the Change of Molar Concentration

Five samples of AgxCu(1-x) Fe2O4 having molar concentrations x=0.1,0.3,0.5,0.7,0.9 were prepared. The optical properties of them were studied. The crystal structure was determined using the XRD technique indicating that the crystal nano spacing decreases upon decreasing the concentration of Cu and increasing the Ag concentration x. The UV-VIS spectrometer results showed that the absorbance increases upon increasing the Ag concentration and decreasing the Cu concentration. The transmission decreases when the Ag concentration increases, which is associated with the decrease of Cu concentration. The FTIR results showed that the transmission to Infrared radiation increases as the Ag concentration decreases and the Cu concentration increases.
