The Influence of the Lead Acetate Water Solution Temperature Background used for Synthesis of Cdxpb1-Xs Films, on their Sensor Properties for No2

Abstract

Summary The results of the water solution heating influence research of an initial component salt on the sensory properties of thin films CdxPb1-xS are presented. For the comparative evaluation, structure and functional properties the films synthesis was carried out from the reactionary mixtures with use a reagent that had undergone thermal treatment and the initial one. The influence of the initial heating of an salt aqueous solution on a thin film morphology is revealed at the content a nitrogen dioxide in air 105ppm, the relative change in ohmic resistance has reached 3,4. The dependence of a heating effect influence of initial PbAc2salt on the response of sensory elements is shown. The reversible character of gas adsorption process was investigated, which provides it possible to create reusable chemical sensors based on a CdxPb1-xS solid solution.
