Abstract

A strong, few seconds lasting post‐luminescence due to Eu²⁺ emission is excited at 15 K by light flashes in KCl:Eu²⁺ crystals coloured by γ‐rays at RT. Within the range of 15 to 70 K the intensity of post‐luminescence varies in inverse proportion to the time and does not depend on temperature. Thermoluminescence glow curves photostimulated at 15 K point to the existence of several glow peaks most of which are due to the thermal activation of trapped‐hole centres of H‐ and V_k‐type. The plausible mechanisms responsible both for post‐luminescence and thermoluminescence as well as the role of Eu²⁺ ions are discussed.
