Surface-plasmon-coupled emission of Rhodamine 110 in a silica nanolayer

Chemphyschem. 2011 Sep 12;12(13):2449-52. doi: 10.1002/cphc.201100252. Epub 2011 Jul 12.

Abstract

The first observation of strong directional surface-plasmon-coupled emission (SPCE) of Rhodamine 110 in silica nanofilms deposited on silver nanolayers is reported. The preparation of the material is described in detail. The intensity of SPCE exceeds 10 times that of free space fluorescence and total linear light polarization in the SPCE ring is observed. A new experimental setup and an original data collection method is presented. Our material completely preserves its fluorescence properties for at least eight months.
