title: Instrumentation for multidimensional luminescence spectroscopy and its application to low-temperature analysis in Shpol'skii matrixes and optically scattering media.
abstract: We present a single instrument with the capability to collect multidimensional data formats in both the fluorescence and the phosphorescence time domains. We also demonstrate the ability to perform luminescence measurements in highly scattering media by comparing the precision of measurements in Shpol'skii solvents to those obtained in "snowlike" matrixes and solid samples. For decades, conventional low-temperature methodology has been restricted to optically transparent media. This restriction has limited its application to organic solvents that freeze into a glass. We remove this limitation with the use of cryogenic fiber-optic probes.
