Highly efficient light emitters based on the spiro concept

We present a comparison of different molecular glasses based on the spiro-concept with respect to their photoemission properties. The absorption and emission spectra as well as the photoluminescence quantum yields in solution are characterized. For thin amorphous films, prepared by vacuum vapor depo...

Summary:We present a comparison of different molecular glasses based on the spiro-concept with respect to their photoemission properties. The absorption and emission spectra as well as the photoluminescence quantum yields in solution are characterized. For thin amorphous films, prepared by vacuum vapor deposition, we examined amplified spontaneous emission (ASE) by optical pumping with picosecond pulses at 337 nm. Efficient ASE emission with thresholds of down to 1 μJ/cm 2 was observed.
