摘要

The formation, structure, and luminescent properties of LiBi1–xEux(MoO4)2 (x = 0,01-1,00) solid solutions synthesized by solid-state sintering have been studied. X-ray diffraction confirmed the formation of a single-phase tetragonal scheelite-type structure (I41/a) corresponding to the isovalent substitution Bi3+→Eu3+. All samples exhibit red luminescence arising from the 5D0→7Fj (j = 1-4) transitions of Eu3+ ions, with the maximum intensity observed for LiBi0.7Eu0.3(MoO4)2. Th. The obtained results highlight the potential of these solid solutions as promising red phosphors for optoelectronic applications.
