(color online) Schematic illustration of a ZnO nanocrystal obtained from freezer milling. It consists of a negatively charged inner core and a positively charged outer shell. The EPR and PL spectra are given for the 1 min milled sample where we clearly observe the core and shell defects simultaneously.^[38]
