Figure 4From: Nanocomposite ZnO–SnO2 Nanofibers Synthesized by Electrospinning Methoda A typical TEM image of a calcined (1 − x)ZnO-(x)SnO2(x = 0.36) nanofiber. The inset shows a selected area electron diffractions pattern, indicating its polycrystalline nature. EDS elemental mapping of the same nanofiber region, showing spatial distribution of b Zn (red), c O (blue), and d Sn (green)Back to article page
