Luminescence of BaBrI Crystals Doped with Ce3+ Ions

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.
