Abstract

Time resolved photoluminescence with picosecond resolution has been employed to study luminescent organic devices. A tunable Ti:sapphire laser emitting 100 fs pulses between 670 nm and 1050 nm, or its second harmonic, have been used to excite photoluminescent and electroluminescent organic samples. The photoluminescence is imaged by a spectrograph and collected by a streak camera offering a resolution of about a picosecond. This technique provides a convenient method of collecting spectral and temporal information simultaneously.
