Phase analysis in Zn_1−xCr_xO through charge density

Abstract

Cr-doped zinc oxide Zn_{1− x} Cr _x O powder samples are synthesized by a standard high-temperature solid-state reaction technique with x = 0.00, 0.04, and 0.08. The powders are analyzed for the electron densities using X-ray diffraction. The electron densities of observed wurtzite phase ZnO as well as the spinel phase ZnCr₂O₄ are mapped and analyzed for Cr doping concentration. The charge density study reveals that the Cr atom is added in the lattice as Cr³⁺ rather than Cr²⁺.
