Enhanced and polarized emission from single colloidal CdSe/CdS nanocrystals coupled to a one-dimensional gold grating

Résumé

We present in detail the fluorescence properties of single thick-shell CdSe/CdS colloidal nanocrystals coupled to a linear one-dimensional gold grating. In addition to the photoluminescence decay rate increase, we point out that the polarization ratio of the emission is dramatically enhanced. It overcomes 80% and can reach values close to unity. Experimental results are successfully compared to theoretical predictions. Blinking suppression is also reported.
