We have developed methods to disperse and partially size separate NbSe 3 nanowires in aqueous surfactant solutions. These dispersions can easily be formed into thin films. Optical and electrical studies show these films to display sheet resistances and transmittances ranging from (, 22%) to (, 79%) depending on thickness. For thicker films, we measured the transparent conducting figure of merit to be σDC, B/σO_p = 0.32, similar to graphene networks. Thickness measurements gave individual values of σOp = 17 800Sm~(- 1) and σ DC, B = 5700Sm~(- 1). Films thinner than ～ 70nm displayed reduced DC conductivity due to percolative effects.
