Fluorescence of Pb1−хCdхSe nanocrystal films

Abstract

The interest in lead chalcogenide structures is driven by the possibilities of using nanocrystal lead selenide films, for example Pb1−хCdхSe, as fast and compact sources of infrared range with low energy consumption. Besides, PbSe films oxidised in the atmosphere of oxygen can serve as optical light receivers of infrared range in gas sensors.
