We repalt the fabrication by PECVD of silicon-rich erbiumdoped silica films that exhibit both 1535 nm f%" and visible photoluminescence. Fluorescence spectra are presented along with absorption spectra that display a strong band edge in the blue, which we ascribe to the presence of Si microclusten. We are unable to observe chamcteristic E?+ absorption bands and propase that excitation of the rare e h is via an energy transfer pmcess from Si microciusters.
