The XEOL spectra as the X-ray being focused at (b) Point A and (c) Point B, shown as the red markers at the SEM image (a) of the ZnO microrods. The corresponding TR-XEOL streak images of (d) Point A and (e) Point B and the fitting the decay times from the TR-XEOL traces of (f) Point A in (d,g) Point B in (e), respectively.
