Abstract

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 hetero junction. 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.

AgInS2 胶体量子点对 ZnO 纳米棒的敏化，用于光激活吸附式气体传感器

摘要

提出了一种基于胶体AgInS ₂量子点装饰的ZnO纳米棒形成涂层的低温技术。结果表明，ZnO纳米晶和带有巯基丙酸分子壳的胶体AgInS ₂量子点形成异质结。具有AgInS ₂胶体量子点的ZnO纳米棒对可见光辐射的敏化提供了该结构在室温下在峰值波长为460 nm的蓝色LED照明下对异丙醇蒸气的气体分析响应。
