ABSTRACT
We report an improved time-resolved luminescence spectroscopy system using sum frequency generation. The system has the following attributes: high time resolution (<400 fs, currently limited by the laser), ability to determine absolute zero in time delay with high precision, wide spectral range, and large dynamic range which allows measurement of luminescence under weak photoexcitation. We illustrate these with examples of time-resolved luminescence spectra from GaAs.

    The luminescence spectra of a KZnF[sub 3] : Tl[sup +] crystal are investigated in the energy range from 4.75 to 5.9 eV at temperatures of 10-300 K upon excitation into the A absorption band (5.7-6.3 eV). At T = 300 K, the luminescence spectra exhibit an intense band with a maximum at 5.45 eV,...

    The influence of laser irradiation on the photoluminescence spectra of perfect C[sub 60] crystals in the orientationally disordered phase is investigated. It is shown that irradiation of the crystals with low-power light for short durations at T=200 K produces radical changes in the luminescence...

    It is shown on the basis of an analysis of the J-band shape, luminescence spectra, and luminescence decay that self-trapping of excitons takes place in J-aggregates with strong topological disorder. A self-trapping barrier must be overcome for this to occur. A microscopic model of the...

    A strongly enhanced luminescence efficiency of zincborate glasses and glass fibers doped with trivalent europium or terbium is reported. The enhancement is attributed to a high content of direct gap ZnO nanocrystallites which operate as sensitizer for the rare-earth ions. The glasses have a low...
