Optimization of Precursor Volume and its Impact on the Characterization of Copper Oxide Thin Films Deposited by Nebulizer Spray Pyrolysis Technique

V. Jagadeesan1 and J. Charles Babu

Abstract

Nanoparticles of copper oxide (CuO) were synthesized and deposited on glass substrates using a standard nebulizer spray pyrolysis (NSP) process. The present study examined the impact of varying precursor volumes on the characteristics of CuO thin films formed by the NSP process. CuO thin films were developed in this work utilizing three distinct precursor volumes (3, 4, and 5 ml) using the NSP method. X-ray diffraction (XRD) analysis revealed a monoclinic crystal structure, which is consistent and proved by using JCPDS card no. (89-5899). The XRD studies have been used to calculate the dislocation density, micro strain, and crystallite size. A surface profilometer was used to determine the average thickness. High-resolution Schottky emitter field emission-scanning electron microscope (FE-SEM) has been used to study morphological properties, and the results demonstrate that each film has been evenly deposited on the glass substrate. Energy dispersive X-ray (EDX) analysis has established the element’s existence in the CuO thin films. Transmission values ranging from 20% to 65% at varied volumes were achieved, according to the optical measurements. Using Tauc plots, the energy band gaps were found to range from 1.85 eV to 2.15 eV, with the lowest band gap value of 1.85 eV for 4 ml. CuO thin-film’s electrical conductivity was measured in DC, and the highest conductivity value for 4 ml was 2.5 x 10-8 S/cm
