1. A precursor composition of TiO2 doped with erbium (Er) and yttrium (Y) for forming a film used in a planar optical waveguide amplifier, comprising:

  • 100 mol % TiO2 precursor compound;

    about 0.1-10 mol % erbium ion (Er3+) precursor compound; and

    about 1-50 mol % yttrium ion (Y3+) precursor compound;

    thereby forming a doped TiO2 film co-doped with erbium and yttrium as an amorphous structure to achieve the enhancing effect on photoluminescence properties.
