An x-ray diffraction and Raman spectroscopy investigation of A-site substituted perovskite compounds: the (Na 1- x K x ) 0.5 Bi 0.5 TiO 3 (0le xle 1) solid solution

The (Na 1 - x K x ) 0.5 Bi 0.5 TiO 3 perovskite solid solution is investigated using x-ray diffraction (XRD) and Raman spectroscopy in order to follow the structural evolution between the end members Na 0.5 Bi 0.5 TiO 3 (rhombohedral at 300 K) and K 0.5 Bi 0.5 TiO 3 (tetragonal at 300 K). The Raman ... View More
