摘要
The circular dichroism, absorption and luminescence spectra of langasite (La3Ga5SiO14) doped with iron ions (Fe) are investigated at temperatures T of 300 and 8 K. Analysis of the data obtained reveals the Fe ions are trivalent. The Fe3+ impurity ions substitute Ga3+ ions and occupy 3f tetrahedral sites. Luminescence from the T-4(1) excited state of the dopant was detected at 8 K. (C) 2015 Elsevier B.V. All rights reserved.
