摘要：

Nanostructured B-site Fe and Mn doped SmCrO3 was prepared by mild hydrothermal growth. The as-prepared crystals are mainly micrometer-scale plates, ranging from rhombus(SmCr0.5Fe0.5O3) to elongated hexagonal( SmCr0.5Mn0.5O3), and finally to well-edged rectangular(SmCr0.17Mn0.5Fe0.33O3) plates. Fe and Mn doped SmCrO3 crystals are indexed into Pbnm space group. The cell parameters of SmCr0.5Fe0.5O3 are slightly smaller than that of pristine SmCrO3. Binding energy analysis of Cr, Mn and Fe in SmCr0.17Mn0.5Fe0.33O3 sample indicates that they all possess +3 oxidation states. Temperature dependent magnetization of the as-prepared samples presents obviously stronger ferromagnetic interactions than the undoped counterparts. This work represents a remarkable development for hydrothermal synthesis into fabricating perovskite oxide crystals with uniform distribution of doping ions.
