We examined the fabrication conditions of optically active Er 3+-doped Bi2O3-SiO2 glass thin films prepared by pulsed laser deposition using a glass target with a nominal composition (mol %) of 41Bi2O3·57SiO 2·2Er2O3. The transparent glass films were obtained at 200°C under 5 × 10-2Torr O2. The glass films were found to possess a composition and a refractive index close to those of the bulk glass used as the target. The films exhibited a broad emission of Er3+ ions at around 1.5-1.6 μm as well as Er 3+ upconversion-pumped fluorescence in the 500-700 nm range.
