Isomorphous substitution of europium for strontium in the structure of synthetic hydroxovanadate
Polycrystalline strontium–europium hydroxovanadates Sr 10− x Eu x (VO 4) 6(OH) 2− x O x were synthesized and studied by X-ray powder diffraction, infrared absorption and diffuse-reflectance spectroscopies and also thermogravimetry.
