Preparation of aqueous sols of Ce1-x Gd x O2-δ, Y0.9Eu0.1VO4 and nanocomposites Ce1-x Gd x O2-δ/Y0.9Eu0.1VO4 stabilized by polyacrylic acid

A method for the synthesis of stable aqueous sols of nanocrystalline solid solutions Ce1-x Gd (x) O2-delta (x = 0.10, 0.15, 0.20) and Y0.9Eu0.1VO4 and nanocomposites Ce1 - x Gd (x) O2-delta/Y0.9Eu0.1VO4 stabilized by biocompatible low-molecular-weight polyacrylic acid was proposed. Polyacrylic acid was shown to be a promising matrix for the preparation of polyfunctional composite materials.
