Thermoluminescence spectra and X-ray luminescence spectra of CaF2Nd single crystals

X-ray luminescence measurements are an important tool in the study of the optical properties of a fluorite system. In the case of CaF2-Nd the major emission under X-ray excitation is in the infrared region, which has been studied extensively. In the present paper, emission in the ultraviolet and visible range under X-ray excitation is reported. Thermoluminescence (TL) and TL spectra in the same region have also been measured. The similarities in the peak emission wavelengths in the two processes show that the emission centres involved are the same. (author)
