Abstract
Deactivation processes of Rhodamine B (RB) in water and interacting with si lver sols were studied by using conventional fluorescence, laser-induced fl uorescence, and pulsed laser photoacoustics. Results showed that the emissi on efficiencies, absorption cross sections, and nonradiative deactivation p athway of RE interacting with silver spheroids of different sizes are compa rable to those obtained for the dye in aqueous solutions.
