Linear and Nonlinear Excitonic Absorption and Photoluminescence Spectra in Cu2O: Line Shape Analysis and Exciton Drift
A complete analysis of the line shape of the excitonic absorption and photoluminescence lines of the yellow series of Cu2O is given. A detailed fit to the absorption lines up to the n 5 exciton according to Toyozawa's theory gives precise values for the excitonic resonance energies, allowing to calculate the excitonic Rydberg. The fit to the photoluminescence lines shows very good agreement w...
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 کاملThe Yellow Excitonic Series of Cu2O Revisited by Lyman Spectroscopy
We report on the observation of the yellow exciton Lyman series up to the fourth term in Cu2O by time-resolved mid-infrared spectroscopy. The dependence of the oscillator strength on the principal quantum number n can be well reproduced using the hydrogenic model including an AC dielectric constant, and precise information on the electronic structure of the 1s exciton state can be obtained. A B...

متن کاملCu2O and Au/Cu2O Particles: Surface Properties and Applications in Glucose Sensing
In this work we investigated the surface and facet-dependent catalytic properties of metal oxide particles as well as noble metal/metal oxide heterogeneous structures, with cuprous oxide (Cu(2)O) and Au/Cu(2)O being selected as model systems. As an example of application, we explored the potential of these materials in developing electrocatalytic devices. Cu(2)O particles were synthesized in va...
