Luminescence spectroscopy

Steady-state and transient photoluminescence (PL) spectroscopy on organic semiconductors is performed by a combination of different laser excitation sources and detectors. For transient PL from the sub-nanosecond to the millisecond range we use an EKSPLA PT-403 picosecond laser with tunable wavelength from 210 to 2300 nm and pulse energies higher than 10 ?J, which is either coupled to a spectrograph with a fast Hamamatsu streak camera system for simultaneous detection of temporal and spectral information, or to a spectrograph with a gated Princeton Instruments iCCD camera for sequential detection of prompt and delayed fluorescence components. For steady-state measurements, we have a bunch of cw-lasers covering the UV and VIS spectral range in combination with either an LN2-cooled Princeton Instruments Si-CCD spectrometer or a TE-cooled Andor InGaAs spectrometer.
