We have developed a novel method to determine the polarization of light emitted from nanometre-ordered spaces in materials by means of polarized cathodoluminescence (CL) spectroscopy with an ellipsoidal mirror in a transmission electron microscope. We have shown that simulation of CL intensities in full consideration of the effect of reflection on an ellipsoidal mirror is necessary to determine the polarization.
