Abstract：The optical properties of a transparent optical resin (HMA/ST) containing ternary rare earth complex are reported. Based on Judd-Ofelt(J-O) theory, the J-O parameters were calculated to be Ω2=10.139 4×10-20cm2, Ω4=3.810 9×10-20cm2, Ω6=9.050 7×10-20cm2 by using the emission spectrum of optical resin containing Eu(TTA)3phen-0.31 wt%. The J-O parameters were used to calculate the total radiative transition rate (456.6 s-1) and radiative lifetime (2 190.1 μs) of the excited state 5D0. The stimulated emission cross-sections σ and the fluorescence branch ratio β parameters for the transitions of 5D0→7FJ′(where J′= 1, 2, 4 and 6) were also evaluated. By analyzing the calculated J-O parameters, it is concluded that the excited state of Eu3+ in optical resin has a long radiative lifetime and large emission cross-section, which shows that the optical resin containing rare earth complex can be used for stimulated emission amplification or as a laser material.
