摘要：Er(DBM)(3)(TPPO)(2) doped solid poly(methyl methacryate) (PMMA) matrix was prepared and its optical absorption and fluorescence spectra were presented. The Judd-Ofelt parameters obtained for Er3+ in PMMA are 43.84 x 10(-20) cm(2), 2.31 x 10(-20) cm(2) and 1.12 x 10(-2)0 cm(2). The radiative properties, such as transition probabilities, fluorescence branching ratios and radiative lifetime have been predicted and evaluated. The calculated radiative lifetime and stimulated emission cross section of I-4(13/2) --> I-4(15/2) transition revealed that it is promising for Er(DBM)(3)(TPPO)(2) doped PMMA to be used in rare earth containing polymer based optical devices.
