Popis:	We report recent results showing broad-band excitation of erbium ions implanted into thin films of silica containing silicon nanocrystals. Evidence for the existence of nanocrystals is presented in the form of HR-TEM images of crystalline regions of the thin films. Indirect excitation of the rare-earth ions is mediated by the nanocrystals, which are either grown in during plasma enhanced CVD of the films, or are formed by implantation of thermally grown SiO 2 layers with Si + ions. We demonstrate efficient flashlamp pumping of the erbium 1.535 μm PL band and discuss the device implications of this material.
