Magneto-photoluminescence of ZnO microrods in high magnetic fields of up to 50 T

Abstract

We have investigated the magnetic field dependence of the photoluminescence (PL) of ZnO microrods. Several excitonic PL peaks were observed. We found that the spectra showed weak energy shift by applying magnetic fields. It is likely that the field variation of the exciton energy shift depends on measurement temperature.
