A model for optical transitions between bound states forF-centers in alkali halides

  • G. Iadonisi
  • B. Preziosi


A model, unique for all alkali halides, is built up, which gives energies for theF andK transitions in good agreement with the experimental results, both in absorption and in emission. In this model theL-bands must correspond to transitions in the conduction band.

Модель оптических переходов между свяэанными состояниями для F центров в шелочных галоидах


Строится единая для всех шелочных галоидов модель, которая дается знергии дляF иK переходов в хорощем согласии с зкспериментальными реэультатами, как при поглошении, так и при иэлучении. В зтой моделиL-полосы должны соответствовать переходам в эону проводимости.


Viene presentato un modello, unico per tutti gli alogenuri alcalini, che dà energie di transizione per le bandeF eK in buon accordo con i risultati sperimentali, sia in assorbimento che in emissione. In questo modello le bandeL devono corrispondere a transizioni nella banda di conduzione.
