Vibrational Spectroscopy and X-Ray Diffraction of Perovskite Compounds Sr1−xMxTiO3(M= Ca, Mg; 0 ≤x≤ 1)

Understanding microwave dielectric properties of (1−x)CaTiO3–xLaAlO3 ceramics in terms of A/B-site ionic-parameters

“…We attribute the bands between 224 and 334 cm −1 to the modes associated with rotations of oxygen cage and the band at 180 cm −1 to the motion of A-site ions. These conclusions agree with the results reported by Hirata et al [22] and Balachandran and Eror [23]. The major scattering bands were observed in Raman spectrum of LaAlO 3 .…”

Structural refinement and photoluminescence properties of irregular cube-like (Ca1−xCux)TiO3 microcrystals synthesized by the microwave–hydrothermal method

“…The Raman peak P 1 is ascribed to the vibration mode of CaTiO 3 orthorhombic lattice [34]. The Raman peaks P 2 , P 3 , P 4 , P 5 and P 6 are Fig.…”

Raman spectroscopy and microwave dielectric properties of Sn substituted SrLa4Ti5O17 ceramics

“…The weak band observed at 605 to 620 cm −1 range can be assigned to the B-O symmetric stretching vibration [12,13]. The broad bands at 450 to 570 cm −1 can be represented as symmetric breathing of the BO 6 octahedra [14]. The E g modes in the range of 200 to 400 cm −1 have been assigned to O-B-O bending mode [12].…”
