Crystal structure and optical spectroscopy of Ca3Ln2Si3O12 (Ln=Gd and Lu) doped with Eu3+
Source abstract
Abstract
Abstract The luminescence of Eu3+ introduced as impurity in Ca3Gd2Si3O12, and Ca3Lu2Si3O12 has been investigated. According to the crystallographic evidences, three sites for the dopant ion are available with different occupation in the two hosts. In both matrixes, the dominant 5D0 → 7F2 emission line reveals a low symmetry of the Eu3+ crystal sites. In the excitation spectrum of Eu doped Ca3Gd2Si3O12 a Gd3+ → Eu3+ ET process is clearly visible.
