Abstract

Hot luminescence |1| (HL) as a natural by-product of relaxation within excited electronic states enables relaxation kinetics to be investigated in detail without recourse to applying any additional (probing) action on the system, which may disturb the process under study. For systems possessing distinct-structured vibronic spectra (e.g. molecules in rigid matrices) the cw HL spectroscopy allows us to evaluate rather precisely vibrational relaxation times up to 10−13s (see review |2|). Yet, by introducing direct picosecond time resolution, HL becomes a truly versatile tool in the study of transient states and relaxation in condensed matter.
