The recombination process, which lasts for several hours at 4 K, results in several broad bands in the RL spectrum. RL-EPR spectra show pronounced angular dependences on crystal orientation relative to external magnetic field. Based on the determined spin-Hamiltonian parameter values the recombination centres have been proposed to be F-type electron and self-trapped hole (VK) centres.1-6openAccessrecombinationluminescencemagnetic resonancephysical radiation effectsfluoridesbarium fluoridesyttrium fluorideselectron spin resonanceparamagnetismcrystal structureArtigo de periódico22310.1016/j.jlumin.2020.1172160000-0003-1502-161676.2679.20
