Size-Dependent Optical Properties of CdSe/CdS/ZnS Nanocrystal Aggregates Encapsulated in a Gold Nano-resonator: A Comprehensive Study

Résumé

This paper explores gold resonator effects on the optical properties of chemically synthesized clusters of CdSe/CdS/ZnS nanocrystals. To reduce optical losses, the gold is sputtered on the aggregates already embedded in a thin silica shell. This technique also allows to compare optical properties (radiation rate, far field emission) of single aggregates of different diameters before and after gold deposition. Experimental results are supported by Finite-Difference Time Domain (FDTD) simulations to understand the size dependent behavior and the role of dipolar and quadrupolar plasmon resonances.
