Figure 4From: Intense ultraviolet emission from needle-like WO3 nanostructures synthesized by noncatalytic thermal evaporation EDS line scanning profile. TEM-EDX line concentration profiles of W and O along the line drawn across the diameter of a typical tungsten oxide nanowire synthesized by a catalyst-free thermal evaporation method. Cu and C in the inset table are due to TEM grid.Back to article page
