Figure 5From: Great blue-shift of luminescence of ZnO nanoparticle array constructed from ZnO quantum dots Schematic illustration of the fabrication mechanism of the ZnO nanoparticle array constructed from ZnO QDs. ZnO molecules randomly diffusing on surface (a), ZnO clusters thermally diffusing on surface and the inset showing the contact angle θ (b), large clusters formation by small clusters continuously diffusing and colliding (c), and big particles formation (d).Back to article page
