SYNTHESIS AND LUMINESCENCE PROPERTIES OF YPxV1-xO4(0 ≤x ≤1): Dy3+
Abstract:
The crystals of YPxV1-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 YPxV1-xO4: 0.006Dy3+ the matrix emission is caused by PO43-, when x>0.4. The influences of Bi3+ and temperature On the emission intensity of Dy3+ were also investigated.
