Absolute fluorescence and absorption measurements over a dynamic range of 1E6 with cavity-enhanced laser-induced fluorescence [dataset] Open Access

We present a novel spectroscopic technique that exhibits high sensitivity and a large dynamic range for the measurement of absolute absorption coefficients. We perform a simultaneous and correlated laser-induced fluorescence and cavity ring-down measurement of the same sample in a single, pulsed laser beam. The combined measurement offers a large dynamic range and a lower limit of detection than either technique on its own. The methodology, dubbed cavity-enhanced laser-induced fluorescence (CELIF), is developed and rigorously tested against the electronic spectroscopy of 1,4-bis(phenylethynyl)benzene in a molecular beam and density measurements in a cell. We outline how the method can be used to determine absolute quantities, such as sample densities, absorption cross sections and fluorescence quantum yields, particularly in spatially confined samples. | This data set contains the original data underpinning the publication. Accepted J. Chem. Phys. 07 June 2018.
