Abstract
The present invention relates to a gas sensing device comprising a nanoparticle layer () and a quantum dot layer () separated from each other by a gas absorption layer () which has a thickness which changes upon absorption of a gas. The nanoparticle layer () is provided for generating a surface plasmon resonance within a plasmon resonance frequency range upon illumination with light within a light frequency range; the quantum dot layer () has an absorption spectrum overlapping with said plasmon resonance frequency range of said nanoparticle layer () and shows photoluminescence in a photoluminescence emission frequency range upon absorption of energy within its absorption spectrum. The present invention further relates to a method for fabricating such a gas sensing device and to a method of using such a gas sensing device.
