摘要：
Spatially resolved cathodoluminescence (CL) spectra of excitons in a ZnO microparticle, which consists of a number of small particles (primary particles), have been investigated at low temperature (15 K). The spatially resolved CL spectra can be interpreted in terms of the influence of an internal electric field, which is likely caused by transfer of electrons from donor defects to surface states near the surface, on the radiative recombination of free and bound excitons in the ZnO microparticle.
