Influence of Annealing Methods on the Morphological and Optical Properties of Cu_2O Nanoparticles Prepared by Chemical Bath Deposition

摘要

In this work, the cuprous oxide (Cu_2O) thin film on glass substrates were fabricated at low growth temperature by a single-step aqueous solution of chemical bath deposition method. In order to optimize optical and morphology quality, the effect of two different heat treatment methods are conventional furnace annealing process and continuous wave (CW) CO_2 laser annealing technique were investigated. The effect of annealing temperatures on the properties of Cu_2O thin films were systematically investigated by UV-Vis spectrophotometer, X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM).
