Abstract
The luminescence spectra of LiY1 − x Eux(MoO4)2 (x = 0.0005, 0.001, 0.01, 0.05, 0.1, 0.5, 1) scheelite solid solutions are measured under laser excitation at 337.1 nm. The effect of Eu3+ concentration on the luminescence behavior of the solid solutions is examined. The highest integrated emission intensity is offered by LiY0.5Eu0.5(MoO4)2. Eu3+ substitution for Y3+ has no effect on the symmetry of the emission centers involved. Eu3+ is shown to occupy only one site in the structure of the solid solutions. X-ray diffraction and luminescence data indicate that all of the solid solutions have an undistorted scheelite structure.
