Abstract

Abstract

We employ the well-studied donor/acceptor system consisting of tris(2,2'-bipyridine)ruthenium(II) and anthracene to validate a simple rate equation model for energy transfer and subsequent dimerization of the excited anthracene acceptor.

Abstract

Abstract

We investigate the nonlinear optical properties of a series of two-photon absorbing chromophores in the femtosecond regime using both two-photon induced fluorescence spectroscopy and the Z-scan technique. We apply a simplified sum-over-states model to the experimental data to predict nonlinear refraction.

WC2.3 - QUANTUM YIELD MEASUREMENT OF ORGANOMETALLIC COMPLEXES USING DOUBLE PUMP PROBE TECHNIQUE

Abstract

Abstract

We performed a detailed study on the triplet state absorption properties of seven organometallic complexes. The singlet-triplet conversion quantum yield was obtained based on a 6-level electronic model. We observed triplet yields of less than unity, contrary to previous reports for this class of compounds.
