摘要

Room-temperature pressure-dependent (0-25 GPa) x-ray absorption spectroscopy at the W L-1,L-3-edges of alpha-SnWO4 and beta-SnWO4 was performed using a dispersive setup and a high-pressure nanodiamond anvil cell. The detailed analysis of experimental x-ray absorption near-edge structure and extended x-ray absorption fine structure data suggests that upon increasing pressure, a displacement of tungsten atoms by about 0.2 angstrom toward the center of the WO6 octahedra occurs in alpha-SnWO4, whereas the coordination of tungsten atoms changes from tetrahedral to distorted octahedral in beta-SnWO4.
