The optical and vibrational properties of BaTi{sub 2}O{sub 5} glass prepared by containerless processing were investigated. The refractive index was 2.15 and the Abbe number was 21.5, as measured by the focal method. The glass was transparent from 340 nm to 7.7 {mu}m. From the Raman scattering spectrum, the maximum phonon energy was found to be 829 cm{sup -1}. Using these data, fundamental optical parameters such as the optical basicity, the average oscillator strength, and the optical band gap were estimated. These parameters suggest that BaTi{sub 2}O{sub 5} glass is an attractive material with many potential applications such as lenses, windows, nonlinear optics, and phosphors; moreover, these parameters can guide future development of new titanate glass compositions with superior optical properties.
