The photoluminescence (PL) and cathodoluminescence (CL) spectra were measured from ZnO particles collected at various distances from the Zn source representing decreasing dimensions. The ZnO tetrapods showed a green emission centred at 516nm (2.40eV) band and the exciton emission at 387nm (3.20eV). The measured data suggested that the green emission is strongly increased for particle sizes below 500nm, whereas the exciton emission is dominant for particle size larger than 500nm. Spatially resolved CL-measurement on individual tetrapod legs showed, that the green emission increases with decreasing ZnO leg diameter. To our knowledge, the local CL spectroscopic measurements were correlated with the dimensions of the individual ZnO tetrapods for the first time.
