Abstract

Mn-doped indium oxide (In 2-xMn xO 3) nanoparticles (7-12 nm) with x = 0.05, 0.10 and 0.15 have been synthesized by solvothermal method using oxalate precursor route for the first time. Powder X-ray diffraction studies showed the formation of monophasic cubic structure of In 2-xMn xO 3 solid solutions. X-ray diffraction and UV-visible reflectance studies revealed that Mn 2+ ions are doped into the In 2O 3 lattice. Reflectance measurements showed red shift in an energy band gap which decreases with an increase in the Mn concentration. Maximum surface area of 768 m 2 g -1 is obtained for In 1.85Mn 0.15O 3 nanoparticles. Magnetization measurement revealed that all the samples are paramagnetic in nature with very weak antiferromagnetic interactions.
