FIG. 1.

SEM images of self-assembled ZnO nanocrystals grown on Pt(111) substrate. The scales (a) and (b) were . The scales of (c) and (d) were . The average diameters (height) of ZnO nanocrystals (a), (b), (c), and (d) were , , , and , respectively.

FIG. 2.

Size distribution obtained from the SEM images of Fig. 1 and the synchrotron x-ray scattering. The inset shows the AES of self-assembled ZnO nanocrystals. The spectra were obtained (e) on the nanocrystal, and (f) between nanocrystals.

FIG. 3.

PL spectra of Volmer–Weber-type self-assembled ZnO nanocrystals The inset shows the background photoluminescence signal of the pure substrate.

Image of FIG. 4.
FIG. 4.

Variation of the emission energy as a function of the ZnO nanocrystals diameter. The dotted and solid lines are curves fitted by the EMA and the phenomenological expression.
