In order to improve luminescence performance of Er3+ doped waveguide amplifiers reducing the clustering of Er3+, the studies about materials used for the fabrication of these optical devices have been implemented actively. Er3+ doped silica based solgel materials co-doped with Al2O3, TiO2, P2O5, and Ge2O3 were reported by a lot of researchers. It was found that those co-dopants play important role in enhancing the solubility of Er3+ ion in the glass matrix, improving its dispersion and reducing the possibility of ionion interaction in Er3+ ion-rich system. In the present work, for the application to Er3+ doped waveguide amplifiers with high gain, incorporating a large amount of Er3+ without clustering of Er3+, we prepared Er3+ doped SiO2ZrO2 solgel materials using ErZr double alkoxide, which was synthesized to prevent the optically harmful Er3+ clustering by the selective coordination of Zr4+ around Er3+ ions.
