A low-temperature technique for the formation of coatings based on ZnO nanorods decorated with colloidal AgInS2 quantum dots is presented. It is shown that ZnO nanocrystals and colloidal AgInS2 quantum dots with a shell of mercaptopropionic acid molecules form a heterojunction. Sensitization of ZnO nanorods with AgInS2 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.
