Judd-Ofelt analysis of Tm and energy transfer studies between Tm and Er codoped in lithium tellurite network

Spectrochim Acta A Mol Biomol Spectrosc. 2007 Sep;68(1):117-22. doi: 10.1016/j.saa.2006.09.046. Epub 2006 Nov 16.

Abstract

Optical properties of Tm(3+) and Er(3+) and Tm(3+)+Er(3+) codoped tellurite glass have been studied using different wavelengths from a Ti-Sapphire laser as excitation source. The energy transfer from one rare earth to other on excitation with different wavelengths has been studied. The Judd-Ofelt theory has been used to calculate various optical parameters suitable for laser oscillation.
