Luminescence spectroscopy and electronic structure of Eu³⁺-doped Bi-containing oxide compounds
The photoluminescence (PL) studies of the set of undoped and doped with Eu³⁺ ions Bi-containing oxide compounds BiPO₄, K₃Bi₅(PO₄)₆, K₂Bi(PO₄)(MoO₄) and K₅Bi(MoO₄)₄ as well as calculations of their electronic structures were performed. The intrinsic PL of undoped crystals was found under excitation i...
