Physical Properties of Cu Doped ZnO Nanocrystiline Thin Films

Abstract

Thin films of ZnO nano crystalline doped with different concentrations (0, 6, 9, 12, and 18 )wt. % of copper were deposited on a glass substrate via pulsed laser deposition method (PLD). The properties of ZnO: Cu thin-nanofilms have been studied by absorbing UV-VIS, X-ray diffraction (XRD) and atomic force microscopes (AFM). UV-VIS spectroscopy was used to determine the type and value of the optical energy gap, while X-ray diffraction was used to examine the structure and determine the size of the crystals. Atomic force microscopes were used to study the surface formation of precipitated materials. The UV-VIS spectroscopy was used to determine the type and value of the optical energy gap.

“…obtained nano carbonate with ESM and studied its fluorescent application. Also, SnO2 NPS was prepared and studied pure and doped with Cu, as copper has high electrical and thermal conductivity and is the most conductive mineral for electricity and heat after silver 17,18 . The study aims to form pure SnO2 nanoparticles doped with Cu by active biosynthesis and use the prepared materials for medical applications…”
