Abstract
The photoluminescence spectra of potassium rare-earth phosphate vanadates K 3R1-yEuy(PO4)(x)(VO4)(2-x) (R = Sc, Y) were measured in the range 450-800 n m under excitation at 337 nm. The energies of the Stark components of the F -7(j) (j = 0, 1, 2) multiplet were determined, and the crystal-field parame ters were evaluated. The effects of the Eu3+ concentration and PO43-/VO43- ratio on the luminescence of the materials studied and the concentration qu enching of luminescence were analyzed. The materials with high Eu3+ concent rations are shown to be potentially attractive as photo- and cathodoluminop hors.
