Copper (or cupric) oxide (CuO) is an eminent material which employs in disparate applications such as photodetectors, battery electrodes, memory devices, transistors and gas sensors. An effortless hydrothermal process was implemented to synthesis virgin CuO and CuO doped nanoparticles (NPs). Detailed investigation was carried out to analyze the ensue of doping of Ag within CuO NPs. The impact of Ag doping on structural, optical, morphological and elemental characteristics were analyzed using X-ray diffractometer (XRD), UV-Vis diffuse reflectance spectrometer (UV-Vis DRS), photoluminescence spectrometer (PL), field-emission scanning electron microscope (FESEM), energy dispersive spectrometer (EDAX) and X-ray photoelectron spectrometer (XPS). XRD confirmed the material’s crystalline nature by displaying the diffracted pattern of monoclinic phased CuO and the average crystallite size computed through Cauchy Lorentzian equation found to increase on Ag doping. The high absorbance and low reflectance of pristine and Ag doped CuO NPs obtained from UV-Vis DRS facilitates the material to well suit for visible photodetection application. The PL reveals the information about the defects and recombination efficiency of the material. The agglomerated flaky nature of the samples was determined through FESEM. The ratio of elements was analyzed through EDAX. The XPS survey spectrum confirmed the appearance of all required constituents of sample and core level spectrum illustrated their chemical states.
