Abstract
Single-phase crystalline fine particles of (CrxV1−x)2O3 have been synthesized by a vapor-phase explosive reaction of a gas mixture of CrO2Cl2 + VOCl3 + H2 + O2 induced by a single laser pulse. The distribution of particle size was uniform with a mean particle size of 80 nm. Lattice constants of (CrxV1−x)2O3 (x=0−1) were accurately determined by the whole-powder-pattern decomposition (WPPD) method. A sharp increase in the a axis-length and a sharp decrease in the c axis-length of the hexagonal unit cell of the oxide (x=0.03) have been observed. The crystal structures of (CrxV1−x)2O3 (x=0.15, 0.5, 0.7) were studied by Rietveld analysis.
