Abstract

Abstract: The crystals of YP_xV_1-xO₄ (0≤x≤1) are tetragonal. With increase of x, their lattice parameters linearly decrease, the Stokes shifts increase and the peak of excitation spectra shifts to shorter wavelenghth. The luminescence effieiencies of the matrix and Dy³⁺ and the yellow-to-blue intensity ratio of Dy³⁺ are related to x. For compound YP_xV_1-xO₄ 0.006Dy³⁺ the matrix emission is caused by PO₄^3-, when x>0.4. The influences of Bi³⁺ and temperature On the emission intensity of Dy³⁺ were also investigated.

Key words: yttrium phosphate-vanadate, dysprosium, bismuth, luminescence, synthesis
