FIELD: measurement equipment.
SUBSTANCE: scope of application: for carbon monoxide detection in air. Invention consists in the following: manufacturing method includes obtaining nanocrystalline wide gap semiconducting oxides MeO (SnO2, ZnO, In2O3), obtaining sols of quantum dots of narrow gap semiconductors CdX (X=Se, Te, S) and oxides impregnation with sols of quantum dots followed by drying for formation of heterocontacts MO/CdX.
EFFECT: providing possibility of decrease of semiconductive sensor materials temperature to the room temperature upon detection of carbon monoxide in air and providing high sensitivity and low energy consumption of sensor.
