摘要

A modified wet-chemical synthesis technology was put forward to fabricate Eu3+/Dy3+ doped with YNbxP1-xO4 and YNbxV1-xO4 phosphors with varying x from the assembly of multicomponent hybrid precursors. The morphologies have been found to be 1-2 mu m crystalline spheres using XRD and SEM. The red photoluminescence intensity reaches the strongest in YNb0.8P0.2O4:Eu3+ and YNb0.1-V0.9O4:Eu3+ phosphors and the red to orange intensity ratio (RO) values decrease with the content of P(V) increasing. Besides this, the optimum concentration for Dy3+ luminescence in YNb0.5P0.5O4 is 1 mol%, while that in YNb0.5V0.5O4 is 0.5 mol% or lower than 0.5 mol%. The yellow to blue intensity ratio (YB) value of Dy3+ increases when the Dy3+ concentration increases from 0.5 to 8 mol% in YNb0.5P0.5O4; however, that of Dy3+ does not vary much in YNb0.5V0.5O4 matrix.
