Erbium and silicon co-doped silica films have been fabricated by reactive magnetron sputtering. A correlation is made between the microstructure monitored by the hydrogen rate r H in the plasma and the photoluminescence properties. The erbium emission at 1.54 m is enhanced by the increase of r H whi
