Title: Y(P,V)O{sub 4}:Dy{sup 3+} phosphors for white light generation: Emission dynamics and host effect

Abstract

The structural characteristics and optical spectra of Y(P,V)O{sub 4}:Dy{sup 3+}phosphors obtained by solid state reaction, sol-gel and hydrothermal routes have been investigated and compared. The luminescence features of these materials show a complicate dependence on the composition, synthetic method and excitation conditions. The emission performance depends on different effects: host luminescence, energy transfer to the doping ions and host dependence of the Dy{sup 3+} emission properties. These effects have been rationalized in order to provide useful information for the development of a suitable material for the white light emitting phosphors technology. - Graphical abstract: The relative intensities of the emission features and the color of the luminescence vary with the host composition along the Y(P{sub x}V{sub 1-x})O{sub 4}:Dy{sup 3+} system. Highlights: > Dy{sup 3+}:Y(P,V)O{sub 4} phosphors have been synthesized by means of three different methods. > The effect of the synthesis procedure on the emission performance has been studied. > The conditions for white light generation have been explored. > The effects of the host composition on the emission dynamics have been investigated.
