摘要: Abstract CdO:ZnO nanocomposite were synthesized via sol-gel technique and optimized for oxygen sensing. The transport properties of the thin films analyzed enhancing gas sensing at low operating temperatures. (1:3) nanostructure was obtained that has a 25 nm grain size with 4.870 A lattice constant. A highly transparent film (3:1) hollow sphere morphology band gap 2.4 eV found to be less resistive. parameters such as sensor response, response time, recovery selectivity stability different temperatures based on resistivity measurements. volume ratio 3:1 best sensitivity 98.96 an temperature 150 °C. present studies are encouraging realization efficient fabricated cost simple spin coating technique.
