Abstract

The characteristic 500 nm emission of CaF₂:Mn has been attributed to the de-excitation of Mn²⁺. However, several mechanisms have been proposed for the formation of the excited Mn²⁺ ion. We have conducted a detailed systematic study of the emission spectra of CaF₂:Mn over the temperature range, 13 - 672 K, which covers the entire thermoluminescence glow peak region. We compared our data for samples with 0.1% and 1.0% Mn to previously reported¹ data for a sample with 3.0% Mn to determine the effects of Mn concentration on the spectra. The entire spectral region was simultaneously recorded by a microcomputer-based diode array, which allowed the accumulation of a large number of spectra with good reproducibility. The data were analyzed to quantitatively determine the centroid, full-width at half-maximum (FWHM), intensity, and skewness of the spectra.
