THE EMISSION SPECTRA OF VARIOUS THERMOLUMINESCENT MATERIALS.
Abstract
The thermoluminescence emission spectra of various materials were determined using a quartz-prism spectrograph. The materials studied include: CaF2:Mn, CaSO4:Mn, Li2B4O7:Mn, LiF(TLD-100), CaF2(MBLE), and a terbium-activated lithium-aluminosilicate thermoluminescent glass. The spectra were measured photographically and corrected by means of an NBS quartz-iodine tungsten-filament standard of spectral irradiance. Precautions were taken to prevent spectral distortions resulting from the variation in sensitivity of the film as a function of wavelength, and from reciprocity-law failure. The present spectra are in general agreement with earlier measurements for CaF2:Mn, CaSO4:Mn, Lif(TLD-100), and CaF2(MBLE). The radioluminescence spectra of CaF2:Mn and CaSO4:Mn was determined and found to be similar in shape and peak position to the thermoluminescence spectrum but were narrower. The radioluminescence spectrum of LiF(TLD-100), however, was wider than the thermoluminesdcne spectrum. The radioluminescence spectra of CaF2(MBLE) extended far into the ultraviolet region. (Author)
