Download F’ Centers in Alkali Halides Book in PDF, Epub and Kindle
These notes offer a comprehensive discussion of the experimental and theoretical work done so far on the F' centers in alkali halides. Here the F' center is a two-electron single-anion-vacancy entity with no other anion vacancies in its immediate neighbourhood. This definition allows for the inclusion of pair interactions between color center species which occupy a central position in the book. Quantities that control or characterize F'-related physics, such as the F-F' conversion efficiency at low temperatures or high excitation levels, the F' thermal lifetime, the F' bandshape, are given a due space. A number of experimental situations related to F' centers are also discussed. Finally, a recently revived attempt to deal with the F-F'conversion in terms of the electron transfer via (bound) polarons, a work still in progress, is described. These notes are expected to stimulate further experimental and theoretical investigations on the F' centers.

Download Optical Study of Excitions in Mixed Alkali Halides: Ki-kbr Book in PDF, Epub and Kindle
The absorption and luminescence properties of KI-KBr mixed crystals were studied over a wide range of KI concentrations. In all systems an absorption band was found which was attributed to a localized exciton formed at an I- - site. The position of the band shifts toward the first exciton absorption peak of pure KI with increasing I- concentration. For dilute I--concentrations the width of the band is twice as large as the width of pure KI or the 82 mole% KI sample. It was also found that the low photon energy absorption edge of this band was an exponential function of photon energy (Urbach's rule) in all mixtures. All the KI-KBr mixed crystals showed a strong luminescence at 80K when excited in the exciton absorption band. In all cases two emission bands were observed. The existence of Urbach's rule and occurrence of two emission bands in these mixed-halide crystals is compared with the similar behavior of pure alkali halides. (Author).
