Effect of Cr doping on structural and optical properties of Eu doped LaVO phosphor.

In this work, the Eu, Cr doped and co-doped LaVO phosphors have been prepared through a high temperature solid-state reaction method. The powder XRD patterns of phosphors are very sharp and intense, which reflects a highly crystalline nature of phosphors. The XRD data were also refined by a Rietveld refinement method.

Influence of Bi ion on structural, optical, dielectric and magnetic properties of Eu doped LaVO phosphor.

In this paper, we have studied the structural, optical, dielectric and magnetic properties of Eu, Bi co-doped LaVO phosphors prepared by solid state reaction method. Rietveld structural analysis of the samples confirms the monoclinic crystal structure with P2/n space group. The particles size of Eu doped LaVO phosphor increased in presence of Bi ion.
