摘要：

In this paper, we report the physical and spectroscopic properties of Er3+.Sm3+ and Er3+:Sm3+ ions codoped barium fluorotellurite (BET) glasses. Different Stokes and anti-Stokes emissions were observed under 532 nm and 976 nm laser excitations. Energy transfer from Er3+ ion to Sm3+ ion was confirmed on the basis of luminescence intensity variation and decay curve analysis in both the cases. Under green (532 nm) excitation emission intensity of Sm3+ ion bands improves whereas on NIR (976 nm) excitation new emission bands of Sm3+ ions were observed in Er:Sm codoped samples. Ion interactions and the different energy transfer parameters were also calculated. (c) 2010 Elsevier B.V. All rights reserved.
