## Rcceivcd 31 May 1973 The visible sbvJrption fluorescenrr and phosphorescence spectra and the polarized fh~orcsccncc and phosphoresccnce cxcitation spectra hwc been measuied for the dimer form of rhodnmine B. The rhodamine B dimer is somelvhat unique in that it exhibits both fluorescence and pho

Thin films including rhodamine B (RB) which were dip-coated using the sol-gel reaction of tetraethyl orthosilicate (TEOS) have been prepared as a function of time and their absorption spectra observed 72 h after preparation of the thin films. One monomer and two dimers (Hand J-types) are clearly and
Deactivation processes of Rhodamine B (RB) in water and interacting with silver sols were studied by using conventional fluorescence, laser-induced fluorescence, and pulsed laser photoacoustics. Results showed that the emission efficiencies, absorption cross sections, and nonradiative deactivation p
