Abstract: | For the first time, the photoluminescence of ions of Ce3+ and Eu2+ in natural low-P ternesite has been measured. The emission bands of Ce3+ ions at 405, 426, and 440 nm and the corresponding excitation wavelengths suggest the presence of Ce3+ ions in three different cationic sites. In the photoluminescence spectra of Eu2+, emission bands at 530 and 620 nm can be seen that originate from two different cationic sites. In addition, it is demonstrated that an energy transfer occurs between Ce3+ and Eu2+ ions situated in those cationic sites where the force of the crystallic field is weakest. The photoluminescence spectra were obtained for a thin section sample with low contents of these two elements (41.2 ppm Ce, 2.11 ppm Eu). |
