摘要：
Luminescence spectra of Cs2NaLuBr6:Eu3+ crystal (1 mol% Eu) in the 400-600 nm range at 12-300 K are obtained. The vibronic pattern of the electronic transitions of the EuBr63- moiety in the crystal lattice is analyzed, and the transitions observed are assigned. Fifteen excited electronic sublevels of the EuBr63- complex are localized. Low-temperature splitting is found for some transitions; the splittings decrease with rising temperature and completely disappear at 80 K.
