Article Synopsis
- The study focuses on the gas-sensing abilities of Cu-doped ZnO thin films created on glass substrates using sol-gel and dip coating techniques.
- The films were produced with varying thickness by controlling the number of coatings and analyzed using methods like X-ray diffractometry and SEM for structure and morphology.
- Results show that Cu-doped ZnO films, especially those doped with copper chloride, exhibited high sensitivity to propane gas, indicating that the type of dopant significantly affects sensing performance.
The physical characteristics of ultrasonically sprayed indium-doped zinc oxide (ZnO:In) thin films, with electrical resistivity as low as 3.42 × 10 Ω·cm and high optical transmittance, in the visible range, of 50%-70% is presented. Zinc acetylacetonate and indium chloride were used as the organometallic zinc precursor and the doping source, respectively, achieving ZnO:In thin films with growth rate in the order of 100 nm/min.

Pulverization of the solution was done by ultrasonic excitation. The variations in the electrical, structural, optical, and morphological characteristics of ZnO:In thin films, as a function of both the water content in the starting solution and the substrate temperature, were studied.
