Anomalous decay kinetics in the low-energy emission of KCl:Tl at 475 nm is detected in the 30-110 K temperature range. This emission has many characteristics of an Ax emission, that is, it originates by escape of excitation from the AT well. For this reason, we can adopt a Jahn-Teller model that was recently reproposed for interpreting this kind of behavior.

Abstract
Anomalous decay kinetics in the low-energy emission of KCl:Tl at 475 nm is detected in the 30-110 K temperature range. This emission has many characteristics of an Ax emission, that is, it originates by escape of excitation from the AT well. For this reason, we can adopt a Jahn-Teller model that was recently reproposed for interpreting this kind of behavior. On this basis, a rather simple and plausible interpretation of the observed data can be given.File in questo prodotto:
