摘要：

This work presents the synthesis of Mg-ZnO root-like nanostructures using chemical spray pyrolysis. Structural, morphological, gas sensing and optical properties were investigated. The films exhibit a hexagonal wurtzite ZnO crystal structure. Morphology changes from grain-like (2 % Mg) to root-like (4 % Mg). The 4 % Mg-ZnO nanostructures detect 5 ppm ammonia gas with a quick response (30 s) and recovery time (7 s). Higher Mg doping influences the optical energy bandgap. Mg-ZnO is a promising material for ammonia gas sensors and optoelectronic devices due to its gas sensing and optical properties.
