We found the luminous earthworm, Microscolex phosphoreus (Dugès, 1837), in Nagoya University campus on Jan 2011. This is the first record of this species in Aichi Prefecture. The luminescent mucus was discharged from anus upon mechanical stimulus. The DNA ‘barcode’ sequences of a cytochrome oxidase I region were analysed and compared to those from other localities.

We have investigated the electronic structures of n- or p-type doped ZnO based on ab initio electronic band structure calculations. We find unipolarity in ZnO; n-type doping using Al, Ga or In species decreases the Madelung energy while p-type doping using N species increases the Madelung energy, in addition to causing substantial localization of the N states. Codoping using reactive codopants, Al, Ga or In, enhances the incorporation of N acceptors in p-type codoped ZnO. We find the delocalized states of N for p-type ZnO codoped with N and Al (Ga).
