Absorption spectra in the near-UV region for solid films and dilute solutions of organic semiconductors. Photoluminescence (PL) spectra of solid films and dilute solutions of organic semiconductors, using a 450 W xenon arc lamp with for sample excitation. Registration of PL spectra and decay-kinetics studies at different temperatures (77 K–295 K). Investigation of PL decay kinetics at room temperature with laser excitation (374 nm, ~50 ps). Studies of photoluminescence oxygen sensitivity. Recording of fluorescence and phosphorescence spectra at low temperature (77 K, 50 ms delay). Determination of PL quantum yields (PLQY) using an integrating sphere.
