Abstract We investigate optical absorption and emission spectra of Sm3+ ions in Sm(DBM)3Phen-doped polymethyl methacrylate (PMMA). Based on the Judd-Ofelt theory, the optical intensity parameters are calculated to be Ω2 = 13.76 x 10-20cm2, Ω4 = 3.41 x 10-20cm2, Ω6 = 4.01 x 10-20cm23 Phen-doped polymethyl methacrylate. The optical intensity parameters have been used to calculate the total radiative transition rate (676.57 s-1) and radiative lifetime (147 μs) of the 4G5/2 exciting state. The stimulated emission cross-sections σij and the fluorescence branch ratios for the 4G5/2 → 6FJ' and 4G5/2 → 6FJ' transitions are also evaluated. The analysis reveals that Sm(DBM)3Phen-doped PMMA is promising for applications in rare-earth-doped polymer devices.
