Structure and luminescence properties of SiO2 sol-gel glass doped with Eu3+

Abstract

Abstract In this work, SiO2 sol-gel glass doped with Eu3+ was investigated its structural and luminescence properties. It was shown that a area containing crystallites of cristobalite with a size of about 45 nm is formed on the glass surface. The Eu3+ spectrum in surface area was obtained. It was demonstrated that the main part of the sample is X-ray amorphous; however, the Eu3+ spectrum in it demonstrates the presence of short-range order.
