摘要：

The new bands have been observed in the secondary emission spectrum of ZnO single crystals under near-resonance excitation. The energy position and the polarization behavior of these lines have been interpreted in terms of a resonant polariton-polariton scattering model. In the emission spectra of ZnO powders of different crystallite size, the manifestation of polariton-polariton interaction has not been detected. The quantum size effect was observed.
