Abstract

The magneto-photoluminescence (PL) of novel magnetic semiconductor Zn1-xCrxO (ZCO) grown by the pulsed laser deposition (PLD) method was investigated. An ArF excimer laser and Cr2O3-mixed ZnO ceramic bulk targets were used for the PLD experiments. The PL peaks at room temperature are very sharp and there is no deep-level emission. The bound exciton peak at 4.2 K was very sharp and increased about three times with increasing applied magnetic field up to 1 T, and the peak wavelength was slightly blue-shifted. It is admirable that the magneto-PL peak was considerably modulated even at low magnetic field. From the peak shift energy of the magneto-PL, ΔE, effective Cr concentration xeff was roughly estimated to be 0.001 on the basis of the electron (n)-type bound magnetic polaron (BMP) model.
