Abstract

en

The emission spectra of KCl :Pb and KBr:Pb are measured as a function of the impurity concentration in the crystals. The low energy emission depends stronger on the impurity concentration in crystals than the principal emission and is less excited within the A absorption band than within the C band. The low energy emission is well explained by the existence of a resonant transfer between − ν|1P1> + μ|3P1> and μ|1P1> + ν|3P1> electronic states.

Les spectres d'émission de KCl:Pb et KBr:Pb ont été mesurés en fonction de la concentration des impuretés dans les cristéaux. Ľémission de basse énergie dépend plus fortement que ľémission principale de la concentration des impuretés dans le cristal, et d'autre part, le randament quantique de ľexcitation dans la bande C est plus grand que celui de la bande A d'absorption. Ľémission de basse énergie est expliquée par un transfert résonant d'énergie entre les états électroniques − ν|1P1> + μ|3P1> and μ|1P1> + ν|3P1>.
