Thermally stimulated aquoluminescence of γ-irradiated alkali halides

Abstract

The recently reported emission of photon pulses, in the range of 400 to 600 nm, during the dissolution of γ‐irradiated alkali halides in water, has been studied as a function of temperature. It is found that the rise time, the pulse height, the number of emitted photons, and the decay time are strong functions of temperature in the range 0 to 90°C. The increased number of photons are due to the increased thermal excitation. Thermal stimulation provides an inexpensive and simple method for the enhancement of the generation and availability of hydrated electrons, and on the other hand, is an indirect method for the study of color centers.
