Abstract

This article describes the formation of homogeneous nanosize (50–250 nm thick) Y<sub>2</sub>O<sub>3</sub>:Eu<sup>3+</sup> coatings on glass surfaces, using water and water–alcohol solutions of yttrium and europium nitrates. The characteristic bands of macroscopic Y<sub>2</sub>O<sub>3</sub>:Eu<sup>3+</sup> powders are observed in the absorption spectra of the resulting coatings. The results of electron-microscopic analysis show that mutually orthogonal nanosize rods that lie in the plane of the coating can be formed in the process of the thermal evolution of homogeneous Y<sub>2</sub>O<sub>3</sub>:Eu<sup>3+</sup> coatings.
