ENERGY ESTIMATE OF PHOTOLYTIC CENTERS IN AG2O

The known affinity energies as well as the binding energies of di- and triatomic silver molecules were used to make a comparative estimate o f the binding energies for the most likely models of molecular photoly tic centers in silver oxide crystals with energies at the absorption, luminescence, and photoconductivity band maxima that are attributed to intrinsic impurity centers. The composition and structure of the cent ers are confirmed by the fact that the known energies agree with the e stimates. It is shown for separate examples that a similar procedure c an be used to estimate the energies of molecular centers in silver hal ides. (C) 1995 American Institute of Physics.
