    Abstract: Provided are transition metal-doped titania nanopowders, which exhibit remarkable absorption in both UV region and visible region, especially are remarkably improved in optical material characteristics in the UV region. The transition metal-doped titania nanopowders are prepared by subjecting a precursor to a combustion reaction, wherein the precursor is obtained by dissolving iron acetylacetonate and zinc acetylacetonate in titanium isopropoxide. The titania nanopowders are doped with Fe and Zn components. A content of the Fe and Zn components contained in the titania nanopowders is 0.05-0.2wt%. A weight ratio of Fe component to Zn component is in the range of 10-25.
