Abstract:
The optical properties of BaBrI crystals doped with cerium ions are studied. The possible types of cerium-containing luminescence centres are established. Using the obtained experimental data for trivalent rare-earth elements, the Dorenbos diagram is constructed. The possible energy transfer mechanisms are proposed on the basis of results of studying the luminescence spectra measured with X-ray excitation.
This work was supported by the Russian Science Foundation, grant no. 17-72-10084, in the part related to the spectroscopy of cerium and the cerium–oxygen sites, determination of the concentration of cerium in crystals, an analysis of the obtained results. Some of the studied crystals were grown within the State Assignment no. 0350-2016-0024.
