Er3+-doped BaTiO3 thin films were grown on Si (100) by metalorganic chemical vapor deposition. Strong characteristic Er3+ intra-4f shell emission at 0.80 eV is observed at 16 and 295 K. The Er 3+ luminescence intensity is linearly dependent on the pump power. Photoluminescence lifetimes were found to be on the order of 8 ms. These results indicate that Er-doped BaTiO3 has potential as an optically active, nonlinear waveguide medium.
