In this work siloxane-polymethyl methacrylate (PMMA) hybrid materials were synthesized and doped with Eu (III) from solid europium chloride, solid europium (III) nitrate, europium chloride (III) in alcoholic solution and 3-aminopyrazine-2-carboxylate of lanthanum and europium complex. The hybrid was prepared from methyl methacrylate (MMA) and 3-methacryloxy-propyl-trimethoxysilane (MPTS), using benzoyl peroxide (BPO) as polymerization initiator. The use of the sol-gel method by acid catalysis allowed to obtain pure solid materials and doped with europium different sources with amorphous characteristics, as evidenced by the X-ray diffraction powderdata. The insertion of the europium complex in the polycrystalline matrix did not changethe str...
