Abstract

The structural characteristics and optical spectra of Y(P,V)O4:Dy3+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 Dy3+ 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 abstractThe relative intensities of the emission features and the color of the luminescence vary with the host composition along the Y(PxV1−x)O4:Dy3+ system.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Dy3+:Y(P,V)O4 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.
