## Abstract High refractive index homogeneous hybrid materials were successfully prepared. The polymer matrix was the copolymer of methyl methacrylate, sulfurβcontaining monomer 2,2β²βmercaptoethylsulfide dimethacrylate (MESDMA), and nanotitania was prepared by __in situ__ solgel process of titanium
Optical absorption and emission spectra of Er 3ΓΎ 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 ΒΌ 21:44 Γ 10 Γ20 cm 2 , X 4 ΒΌ 1:195 Γ 10 Γ20 cm 2 , X 6 ΒΌ 1:202 Γ 10 Γ20 cm 2 from the
