Study of the Structural and Optical Properties of Bi2O3:Cu Thin Films as a Function of Different Doped Ratios

Abstract

Thin films of pure bismuth oxide (Bi2O3) and doped with copper (0.2,4,6 %) were deposited on glass substrates by using a pulsed laser deposition device (PLD) with a power of (600mj) at room temperature and under low pressure ( 10-3mbar) ,The X-ray diagnostic results of bismuth oxide films doped and undoped with copper showed that they are of a monocrystalline structure and of cubic type. By analyzing these curves, it became clear the location of the peak around the angle of 27 degrees at the level (111), but the value of the optical energy gap increased by increasing the distortion rates and it has a high permeability.
