Synthesis and Luminescence Properties of KBi(MoO₄)₂:Eu³⁺

Abstract:

Polycrystalline KBi(MoO₄)₂ has been grown from molten system K-Bi-Mo-O. Solid solutions KBi_1-xEu_x(MoO₄)₂ (x = 0.001 - 0.100) have been prepared by solid state synthesis and characterized by powder IR spectroscopy, DTA analysis, X-Ray powder diffraction and luminescence spectroscopy. It was found that all investigated Eu³⁺-containing molybdates reveal intensive photoluminescence lines related to f-f electronic transitions in Eu³⁺ ions. The KBi_1-XEu_X(MoO₄)₂ crystals with low Eu³⁺ concentration reveal also intrinsic host luminescence under excitation in the ultraviolet (UV) spectral region at T = 4.2 K.
