Resumen:
The temperature dependence of the emission spectrum of europium-activated NaCl, KCl, RbCl, KBr, KI, and RbBr has been measured in the temperature range 77-600 K. From these data the activation energy corresponding to the thermal quenching of the Eu-luminescence, as well as the vibrational frequency interacting with the center in its excited state have been determined for each crystal.
