Ouhenia-Ouadahi, K; Yasukuni, R; Yu, P; Laurent, G; Pavageau, C; Grand, J; Guerin, J; Leaustic, A; Felidj, N; Aubard, J; Nakatani, K; Metivier, R CHEMICAL COMMUNICATIONS, 2014, 50, 7299-7302.

Silica-coated gold nanorods functionalized with grafted fluorescent and photochromic derivatives were synthesized and characterized. Spectroscopic investigations demonstrated that cross-coupled interactions between plasmonic, photochromic, and fluorescence properties play a major role in such nanosystems, depending on the thickness of the silica spacer, leading to multi-signal photoswitchability.
