REFRACTIVE INDEX NANOSENSOR USING PLASMONIC ENHANCEMENT OF PHOTOLUMINESCENCE

https://doi.org/10.29235/1561-8323-2018-62-2-164-169

Abstract

A refractive index nanosensor is proposed on the basis of plasmonic enhancement of quantum dot (nanocrystal) photoluminescence in the presence of a metal nanoparticle. Calculations of a silver elongated spheroid in the liquid show that the changes in the sensitivity of such a nanosensor to a refractive index can be of the order of 10–4 provided that the photoluminescence intensity detection is of the order of 1 %.
