Optical absorption and emission spectra of Er 3þ ion in Er(DBM) 3 Phen-doped polymethyl methacrylate (PMMA) have been studied. Based on Judd-Ofelt theory, the optical intensity parameters are calculated to be X 2 ¼ 21:44 Â 10 À20 cm 2 , X 4 ¼ 1:195 Â 10 À20 cm 2 , X 6 ¼ 1:202 Â 10 À20 cm 2 from the
