All optical investigations of copper oxide for detection devices

摘要

A High quality high transparent conductive copper dioxide (Cu2O) thin film was prepared by reactive pulsed laser deposition method. The prepared samples were analyzed and measured using the UV-visible and the photoluminescence. The Optical properties shows a high transparency reached to about (62 and 66) % and decreases sharply with the decreasing of annealing. Optical band gab of prepared film at optimum condition is about 2.62-2.67 eV. The optical investigations and constant of the energy band gap, the refractive index, and the extinction coefficient were also elaborated.
