Thermoluminescence Spectra of X-Ray Colored KCl Crystals

Abstract

Thermoluminescence spectra of x-ray colored KCl crystals have been recorded, using a liquid-air cooled photomultiplier as detector.

Glow peaks are shown to appear in pairs—a violet one (0.395 μ) and a blue one (at 0.44 μ)—repeated several times throughout the temperature range of 90–550°K.

The phosphorescence at 90°K was found to be composed of three bands (at 0.51, 0.395, and about 0.28–0.35 μ). The 0.51-μ band shows two glow bursts on warming the crystal.

The half-intensity breadth of the violet band (and probably also of the 0.44- and 0.51-μ bands) was found to equal that of the F band, this to include also the temperature broadening.

It is suggested that the thermoluminescence arises from transitions involved in the recombination of free holes and F electrons.
