Nano-Flower Structure of Indium and Gallium doped Zinc Oxide Powder

A nanostructured Al-doped ZnO as an ultra-sensitive room-temperature ammonia gas sensor

“…When pure semiconductor capabilities are insufficient to meet the demands of the desired applications, one of the most effective approaches to improve semiconductor performance is doping with appropriate elements. ZnO has been doped with aluminium [ 8 ], gallium [ 9 , 10 ], cadmium [ 11 ], copper [ 12 ], and other materials to optimise its optical, electrical, and physical properties. In the literature, Indeed, various publications have proposed chemoresistive sensors based on WO 3 [ 13 ], SnO 2 [ 14 ], Co 3 O 4 [ 15 ], and ZnO [ 16 ] that have been investigated for the detection of VOCs.…”

Photocatalytic degradation of methylene blue and dye mixture using indium-doped CaWO4 synthesized by sonochemical and microwave-assisted hydrothermal methods

“…18 The literature presents notable improvements in the optical properties of some semiconductor oxides from the presence of indium. 18–20 Thus, the In 3+ substitution mechanism in CaWO 4 becomes significant in studying the photocatalytic activity from dopant engineering. The microwave assisted hydrothermal method is a clean method, economical, and has a fast delivery speed and realization system, and it is possible through this method to quickly prepare nanoparticles with a narrow uniform size distribution and morphology.…”
