Ir Spectroscopy of Monoclinic Tungsten Oxide

摘要

Stoichiometric tungsten trioxide WO_3 has several polimorphous crystal phases [1] in the temperature region from 4 up to 1200K. These WO_3 phases have more or less distorted ReO_3 - type crystal structures, and ReO_3 lattice topology is identical to topology of the BO_3 sublattice of perovskite ABO_3.
