Luminescence at the axial centers of CdP2-D48 crystals [PDF]
Heliyon, 2018 Emission lines of free excitons and excitons bound to axial centers have been observed in the luminescence spectra of CdP2-D48 crystals doped with Mn, Sn, and Sb at 10 K. Bands models of excitons bound to axial centers (Mn, Sn, Sb) are proposed.

On the luminescence and absence of luminescence of F centers
Solid State Communications, 1975 AbstractA model, proposed originally by Dexter, Klick and Russell, is used to explain the occurence or non-occurence of F-center luminescence in ionic crystals, in terms of a simple two-state configuration coordinate diagram. In this model, which works for all known cases, luminescence is quenched by a competing non-radiative process whenever the ...
