Thermoluminescence of X-Ray Colored NaCl Crystals

Abstract
Glow curves and thermoluminescence spectra taken at various temperatures during the glow have been recorded simultaneously. Spectra were obtained with a rapid-scanning spectrophotometer using a liquid-air cooled photomultiplier in conjunction with a cathode-ray oscilloscope. Peaks of the same wavelength were found to be repeated several times in the temperature range of 80-600°K.
