摘要:

Silica‐titania sol‐gel planar waveguides were deposited on silica glass disks by spin coating. Fluorescence lifetimes as high as 375 &mgr;s were measured in neodymium‐doped sol‐gel planar waveguides and 1.78 ms for an erbium‐doped film. Quenching was found to occur for the former at concentrations above 1 at. % of neodymium. ©1996 American Institute of Physics.
