Time resolved photoluminescence in semiconductor microcavities in the strong coupling regime both for non-resonant and resonant excitation is modeled by considering scattering of exciton polaritons by acoustic phonons. Rise time and decay time of the lumin ...

The 2-K recombination dynamics of coupled GaN-AlGaN multiple quantum wells reveals a composite nature in terms of the joint contributions of short-lived direct excitons and long-lived oblique ones. The possibility to observe these oblique excitons, which p ...
We have investigated the intersubband scattering of electrons in GaAs quantum wells using luminescence up-conversion with 100-fs resolution. The decay time of the n=2 electron-to-heavy-hole transition (e,hh)(2) depends both on the excess energy of the char ...
Scattering rates of quantum-well excitons by acoustic phonons are calculated using realistic deformation potentials for electrons and holes in structures based on GaAs. These fates are used in order to reproduce the exciton dynamics in a time-resolved phot ...
The solubility of rare gases in silicate melts and minerals at high pressure is of importance for understanding the early history of the Earth and its present day degassing. Helium, neon, argon, krypton and xenon were originally incorporated into the Earth ...
Time-resolved fluorescence spectra for C60 mols. embedded in Ne and Ar matrixes and C70 in Ne matrixes were recorded using a synchroscan streak camera. In the case of C60, the decay times of the S1 state are identical for all fluorescence bands confirming ...
The first 1H NMR measurements are reported that allow on to compare T2 decay rates under free precession with T1p decay rare of spin-locked in-phase and antiphase coherence. Measurements were make for the cyclic undecapeptide cyclosporin A and for the self ...
The demonstrate the storage of 1000 holograms in LiNbO3:Fe, recorded at 488nm and read at 633nm to reduce decay during read-out. We minimize Bragg mismatch problems of the two-wavelength scheme by using thin crystals, while combining peristrophic and angle ...

A theoretical investigation of the dynamics in a photoluminescence experiment in strong-coupling semiconductor microcavities is presented. Radiative recombination rates of microcavity polaritons in the strong-coupling regime and their scattering rates with ...
Luminescence properties for C-60 single crystal, the temperature dependence of the luminescence spectra and decay kinetics were measured for a wide range of excitation energies. At low temperatures the emission spectra with well resolved structure were det ...
