Abstract
Polycrystalline KBi(MoO4)2 has been grown from molten system K-Bi-Mo-O. Solid solutions KBi1-xEux(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 KBi1-XEuX(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.
