Ionized and neutral donor bound excitons: Haynes´ rule
... Another interesting point is the I10 recombination6, which from the localization energy is explainable as a D0X recombination according to Haynes´ rule in ZnO. From fig. 4 one could then derive the corresponding ionized donor bound exciton line. The expected line position should be around 3.3630 eV, ...
