摘要：

The mechanism for conversion between the orthoexciton state and the lower-lying paraexciton state in Cu2O has never been completely understood. We propose that at low density this conversion takes place via the emission or absorption of a single acoustic phonon. We show that the rates derived using this mechanism give good agreement with the measured down-conversion rate as a function of temperature, as well as with the measured luminescence intensities of the orthoexcitons and paraexcitons as functions of temperature and stress. © 1990 The American Physical Society.
