Free and bound exciton luminescence of ZnP2 –D4↑8
Thin structure of polarized absorption spectra of indirect transitions with phonon emis- sion in the ZnP crystals is investigated. In the luminescence spectra, radiation of phonons at annihilation of free excitons simultaneously with radiation of excitons bound on axial centre is found. A model...

| Sumario: | Thin structure of polarized absorption spectra of indirect transitions with phonon emis-
sion in the ZnP crystals is investigated. In the luminescence spectra, radiation of phonons at
annihilation of free excitons simultaneously with radiation of excitons bound on axial centre
is found. A model of optic recombination transitions of the axial centre is proposed. |
