Abstract
We demonstrate the implementation of a broadband fluorescence up-conversion set-up with high signal-to-noise ratio and dynamic range allowing for the detection of weak luminescence from triplet states in Fe(II) NHC complexes. Based on the experimentally determined radiative rates and the emission spectra, these states have dominant MLCT character.
Highlights
Broadband fluorescence up-conversion spectroscopy (FLUPS) capable of measuring full emission spectra for fixed delay times was introduced more than 20 years ago [5], and significantly improved in recent years in terms of sensitivity, bandwidth and time resolution [6,7]
We implemented in the present approach a non-collinear type II sum frequency generation (SFG), enhancing the spectral acceptance bandwidth
Given the relatively longlived emission signal to be detected a compromise between sensitivity and time resolution led us to use a slightly thicker 400-μm BBO crystal as SFG medium, entailing a 190-fs time resolution estimated from the solvent Raman emission
Summary
Broadband FLUPS capable of measuring full emission spectra for fixed delay times was introduced more than 20 years ago [5], and significantly improved in recent years in terms of sensitivity, bandwidth and time resolution [6,7]. We implemented a broadband FLUPS experiment with a sufficiently high dynamic range and sensitivity that
