Abstract
The $Y_{1-x}(P_{1-y-z}Nb_yV_z)O_4:Eu_x$ blue and red emitting phosphors were prepared by the combinatorial chemistry method. The combinatorial library was designed to investigate the luminescence of the $Y_{1-x}(P_{1-y-z}Nb_yV_z)O_4:Eu_x$ phosphors under 254 nm and 147 nm excitations. In addition, the crystallinity and morphology of phosphors were checked by XRD and SEM. Based on the results from the combinatorial screenings, luminescent properties of phosphors are strongly dependent on the concentration of doping metal ions. It was found that a new phosphor $Y_{0.88}(P_{0.92}Nb_{0.05}V_{0.03})O_4:Eu_{0.12}$ shows excellent luminescent efficiency comparing to the $Y_{0.88}PO_4:Eu_{0.12}$ red phosphor.
