Abstract

Titanium dioxide films doped with erbium were prepared by sol-gel technique from Ti(OC₂H₅)₄ or Ti(OC₄H₉)₄ precursors. Room-temperature luminescence at 1.53 micrometers associated with ⁴I_13/2 - ⁴I_15/2 transitions of Er³⁺ ions in TiO₂ films derived from the first precursor has been detected. The films have a refractive index about 2.4 and may be used in the planar erbium doped waveguides.
