Abstract
Copper oxide nanoparticles were prepared by chemical combustion and co-precipitation method and observed the humidity sensing property. The CuO nanoparticles were characterized under X-Ray Diffractometer (XRD), Particle Size Analyser (PSA), Thermo Gravimetric And Differential Thermal Analyser (TGDTA), Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). XRD results with JCPDS card numbers confirmed that obtained nanoparticles are CuO nanoparticles and the average crystallite size of CuO nanoparticles are in nano meter range. The weight losses of the sample and phase transformation details were obtained by TGA. SEM images inferred that the nanoparticles are in cubic shape, nearly uniform in size & crystallinity in nature. The humidity sensing property is exhibited by the copper nanoparticles.
