PHOTO-LUMINESCENCE STUDY OF EXCITONS IN AGBR IN HIGH MAGNETIC-FIELDS

Abstract:

The luminescence spectrum of AgBr at 1.6K reveals a number of sharp lines which are associated with excitons bound to residual impurities and crystalline defects. Two lines are identified as excitons bound to iodine ( epsilon b=43 meV) and cadmium ( epsilon b=8 meV). Several lines are observed in the neighbourhood of the phonon-assisted free-exciton emission, two of them corresponding to excitons bound to unidentified centres with energies of 1 meV and 0.25 meV. Electron-hole exchange couplin...
