Studies on Mg and Mn Doped ZnO Thin Films via Spray Pyrolysis Technique

Abstract

The field of gas sensing has endorsed remarkable prosperity and transformation over the last few decades. Basically, introduced to detect combustible gases and toxic leaks, gas sensing technologies have now evolved into highly sophisticated, and miniaturized capable of detecting minimal amounts of gases with high selectivity and sensitivity. The revolution of gas sensing has been driven under global challenges such as climate change, air pollution, industrial safety, and health diagnostics. The introduction of nanostructures (e.g., nanowires, nanorods, nanoparticles, and nanotubes) has significantly increased the surface-to-volume ratio of sensing materials, which occurs dur to the reduction of size to micro and nano-scale. Such knowledge of importance of size reduction has lend to employ suitable materials in wide range of applications, of that gas sensor is the one. The characteristics of a gas sensor namely, faster response and recovery times, as well as the ability to detect very low concentrations (ppm to ppb levels) at low operating temperatures of target gases. newlineThe thesis is em newline
