Abstract
Thermal decomposition of W(CO)6 in oleylamine in the presence of mild oxidant Me3NO·2H2O produces tungsten oxide nanorods with diameters ranging from 3 to 6 nm. The size of nanorods can be easily varied by the employed surfactant ratio or reaction temperature. The prepared tungsten oxide nanorods exhibit strong photoluminescence (PL) peaks in 300−500 nm, which show a weak size dependency.Keywords
