Evaluation of defects in cuprous oxide through exciton luminescence imaging
The various decay mechanisms of excitons in cuprous oxide (Cu2O) are highly sensitive to defects which can relax selection rules. Here we report cryogenic hyperspectral imaging of exciton luminescence from cuprous oxide crystals grown via the floating zone method showing that the samples have few defects. Some locations, however, show strain splitting of the 1s orthoexciton triplet polariton lu...
متن کاملTemperature dependence of exciton Auger decay process in Cuprous Oxide
We report theoretical and experimental study on Auger decay of excitons in Cu2O in a wide range of temperatures, from 2 Kelvin to 325 Kelvin, in single-photon surface excitation. We find that the Auger constant linearly increases with temperature above 100 Kelvin. This constant is important for experiments on Bose condensation of excitons.
متن کاملStatistics of Exciton Emission in a Semiconductor Microcavity: Detuning and Exciton-Exciton Effects
We consider the interaction of quantum light with an ideal semiconductor microcavity. We investigate photon statistics in different conditions and the presence of detuning and exciton-exciton interaction. We show that in the resonant interaction and absence of the exciton-exciton interaction, the state of the whole system can be considered as coherent state. According to our results, it turns...

متن کاملEsr Triplet Exciton Spectrum of Acridine Orange
The triplet state of acridine orange dissolved in methanol/water matrix was investigated by ESR. In absence of oxygen a strong temperature dependence of the spectra was observed. At low temper ature (100 °K) the zero-field splitting parameters calculated from the triplet spectrum are: X /h c = 0.0050 cm-1 , Y / h c = 0.0342 cm-1 , Z //ic = 0.0387 cm-1 , at higher temperature (140 °K) : X * ( h...
