Aggregation and photophysics of Rose Bengal in alumina-coated colloidal suspensions

Mostrar todas las versiones(2)

The absorption and emission properties of Rose Bengal (RB) have been studied in colloidal suspensions of positively charged alumina-coated silica nanoparticles (Sil). Experimental spectra can be rationalized by the existence of an equilibrium between aqueous monomers and only one adsorbed species. H...
