(Color online) (a) TEM image and (b) observed and calculated XRD pattern for the (V1− x Cr x )2O3 nanocrystals at RT.
(Color online) O K XAS spectra of the (V1− x Cr x )2O3 nanocrystals measured at 180 K (red line) and 100 K (blue line), and of the V2O3 nanocrystals5 at 170 K (black line).
Temperature dependence of the magnetic susceptibilities of the (V1− x Cr x )2O3 nanocrystals (black line) and the V2O3 nanocrystals with crystal sizes >∼40 nm (grey line).
(Color online) Characteristic part of XRD patterns of the (V1− x Cr x )2O3 nanocrystals at 170 K (red line) and 100 K (blue line) as well as for the high-temperature corundum phase at 284 K (grey dotted line) and the low-temperature monoclinic phase at 100 K (grey broken line) of bulk V2O3.5 The data of the bulk are corrected for comparison.
Lattice constants and V-V distances in the corundum phase of the (V1− x Cr x )2O3 and the V2O3 nanocrystals (NCs)5 at RT.
