Abstract

When CuCl and CuBr are excited in their band to band absorption, biexcitons are generated from carriers and excitons. They are characterized by a Boltzmann distribution function with a temperature higher than that of the sample. They decay radiatively from their ground state to exciton-polariton states. Broad emission bands are observed.

When biexcitons are directly created by a resonant two-photon absorption in their ground state, they may form a Bose-Einstein condensate. When they recombine radiatively, sharp emission bands are indeed observed on the high energy edge of the broad emission bands.
