Neutron total scattering measurements were performed at 300 K and 15 K to study local structural disorder in deuterium plasma treated and as-prepared Zn{sub 0.9}Co{sub 0.1}O nanocrystalline powder. We found that static disorder becomes a determining factor for atomic pair correlations on the length scale larger than r{approx}9A. On the source of the static disorder, we propose a partial occupancy of Zn/Co further away from its crystallographic site along the c-axis. Between the deuterium plasma treated and as-prepared Zn{sub 0.9}Co{sub 0.1}O samples, we observed no local structural difference, which suggests that no additional disorder is induced by the deuterium plasma treatment.
