In this present work, bismuth oxide (based on Bi2O3) and zinc oxide (ZnO-doped) thin films were produced by thermal evaporation (RT) method on 50-nm-thick glass substrates and annealed at 573 K. SEM showed that the (Bi2O3/ZnO) nanoparticles were evenly dispersed throughout when the ZnO doping concentration was increased. The actual result of the optical characteristics of (Bi2O3/ZnO) showed that (extinction coefficient, refractive index, real part and imaginary part of the dielectric constant) increase with increasing concentrations of ZnO nanoparticles. This behavior makes them excellent optical materials for photonics applications. The results of the D.C electrical characteristics show that the D.C electrical conductivity of the (Bi2O3/ZnO) nanocomposites increases with increasing nanoparticle (ZnO) concentrations and temperature. At the same time, the resistance and activation energy decrease with increasing nanoparticle (ZnO) concentrations. The measured gas sensor revealed a sensitivity to H2S of about 69.74% at 200 °C, decreasing to about 55.14% at 250 °C and 51.42% at 300 °C. Finally, the results of the structural and conductive characteristics of (Bi2O3/ZnO) thin films can be used in various nanoelectronics devices and gas sensors. Finally, the results expected that metal oxide nanostructures will prove to be the most effective building blocks for developing cutting-edge gas sensors. The effects of various doping’s on the morphology and crystal structure of ZnO materials are examined in depth in this article. This article provides sound advice for developing high-performance semiconductor oxide sensing materials based on zinc oxide (ZnO).
