Observation of enhanced defect emission and excitonic quenching from spherically indented ZnO

Coleman, Victoria A; Bradby, J. E.; Jagadish, C.; Phillips, M. R.


The influence of spherical nanoindentation on the band edge and deep level emission of single crystal c-axis ZnO has been studied by cathodoluminescence(CL) spectroscopy and monochromatic imaging. Excitonic emission is quenched at the indent site and defect emission in the range of 450–720nm is enhanced.
