Synthesis and gas sensing properties of ZnO quantum dots

Quantum-sized ZnO nanoparticles synthesized in aqueous medium for toxic gases detection

“…Recently, Nath et al synthesized the ZnO quantum dot via quenching technique and investigated the sensing property for acetone [17]. Another article is reported by Forleo et al, they obtained ZnO quantum dots by alkaline-activated hydrolysis and condensation of zinc acetate solutions, and is used in investigating of sensing properties for acetone and NO 2 [18]. …”

Influence of Multiple Layers on Chemical Bath Deposited Zno Thin Films

“…This wide direct band gap makes it potentially important material for several applications such as solar cell, chemical sensors, electroluminescent devices and ultraviolet laser diodes [2,3]. Also ZnO have been studied as the active channel material in thin film transistors development because of its n-type nature, very good thermal stability and ability to crystalline orientation on different substrates [4].…”

A study on the sensing of NO2 and O2 utilizing ZnO films grown by aerosol spray pyrolysis

“…Up to now, researchers attempt have been focused on ZnO nanostructured materials since they present new opportunities for enhancing the properties and performance of gas sensors because of the much higher surface-to-volume ratio than that of bulk materials [20,21]. However, the sensing temperature of ZnO nanostructures is relatively high (usually higher than 300 C) and their sensitivity needs to be further enhanced for practical application at the industrial level as well as for commercial purpose.…”
