Radiative properties of Sm(DBM)(3)(TPPO)(2) doped poly(methyl methacryate) (PMMA)

摘要

Sm(DBM)(3)(TPPO)(2) doped poly(methyl methacryate) (PMMA) was prepared and its optical absorption and fluorescence spectra were presented. From optical absorption measurements and using the Judd-Ofelt theory, the radiative properties, such as transition probabilities, stimulated emission cross-section, fluorescence branching ratios and radiative lifetime have been predicted and evaluated. The results revealed that the (4)G(5/2) --> H-6(9/2) transition of Sm3+ in PMMA can possibly be applied as a laser transition. (C) 2004 Elsevier B.V. All rights reserved.
