The nanoparticle layer (1) 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 (3) has an absorption spectrum overlapping with said plasmon resonance frequency range of said nanoparticle layer (1) 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gas sensing device","description":"The present invention relates to a gas sensing device comprising a nanoparticle layer (1) and a quantum dot layer (3) separated from each other by a gas absorption layer (2) which has a thickness whic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8525129","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
