This study aimed to present study aims to prepare a novel gas sensor of copper oxide mixed with neodymium oxide and lanthanum oxide to improve the sensitivity of copper oxide towards some toxic gases at various concentrations and various working temperatures. Explaining the role of neodymium oxide-copper oxide and lanthanum oxides-copper oxide heterojunctions in improving the sensing properties of the prepared thin films. Determining the optimal conditions of the prepared sensor (working temperature, gas concentration) to attain a suitable sensor for NH3 and CO2 detection at various concentrations and temperatures
