摘要：

Laser radiation is used for the deposition of dielectric erbium doped BaTiO3 thin films for photonic applications. Pulsed laser deposition with KrF excimer laser radiation (wavelength 248 nm, pulse duration 20 ns) is used to grow dense, transparent, amorphous, poly-crystalline and single crystalline erbium doped BaTiO3 thin films. Visible emission due to up-conversion luminescence (wavelength 528 nm and 548 nm) under excitation with diode laser radiation at a wavelength of 970-985 nm is investigated as a function of the erbium concentration of 1-20 mol % and structural film properties.
