Sensitization of ZnO Nanorods by AgInS2 Colloidal Quantum Dots for Adsorption Gas Sensors with Light Activation

a low-temperature technique for the formation of coatings based on ZnO nanorods decorated with colloidal AgInS 2 quantum dots is presented. It is shown that ZnO nanocrystals and colloidal AgInS 2 quantum dots with a shell of mercaptopropionic acid molecules form a hetero junction. Sensitization of Z...

Description
Summary:a low-temperature technique for the formation of coatings based on ZnO nanorods decorated with colloidal AgInS 2 quantum dots is presented. It is shown that ZnO nanocrystals and colloidal AgInS 2 quantum dots with a shell of mercaptopropionic acid molecules form a hetero junction. Sensitization of ZnO nanorods with AgInS 2 colloidal quantum dots to visible irradiation provides a gas analytical response of the structure to isopropyl alcohol vapor at room temperature under blue LED illumination with a peak wavelength of 460 nm.
