摘要

Fluorescence from Coumarin 6 (C6), a laser dye, decreases considerably due to microcrystal formation in aqueous environments. The fluorescence yield can be effectively enhanced by applying beta-cyclodextrin that revives the molecular entity of C6 through host-guest chemistry. C6-b-CD capsules formnanocubes in solution with surface projected hydroxyl groups. Increase in solvent viscosity brings the nanocubes closer following agglomeration, while keeping the molecular entity of C6 intact. This enhances the fluorescence from C6 encapsulated in beta-CD nanocubes by 40%. Moreover, this emission can be tuned quantitatively by applying nanoparticles (silver in the present case) at each environmental viscosity level.
