Structure, optical, and morphological investigations of nano copper oxide prepared using RPLD at different laser wavelength effects

Nano copper oxide were prepared and deposited using reactive pulsed laser deposition on the quartz substrates at different laser wavelength. The laser wavelength on the crystallization of the copper oxide has been investigated. The analysis of the XRD (X-ray diffraction) revealed that the deposited nanofilms at the wavelength of 532 nm were structures of monoclinic with the discriminatory along the orientation direction of (111). The SEM observes the formation of the nano and microstructures from the substrate surface resulting in the formation of membranes with a small size nano and microstructures. The PL spectra reveal a single main sharp peak; its center has a high density of about 497 nm at 532 nm laser wavelength, also one wide main peak centered around 430 nm with high density at 1064 nm laser wavelength.
