摘要：

The advances of surface-enhanced Raman scattering (SERS) on semiconductor substrates, which is also the major research of our group in the past three years, are summarized in this paper. The application of semiductor nanoparticles explored the scope of SERS substrates. Some possible mechanisms different from noble metal substrates were discussed. The major contribution of semiconductor substrates for SERS maybe charge-transfer. Some phenomena, such as nanoparticle size dependence, half-width decrease of spectra, exciting line dependence, were discussed. The possible reasons of chemical enhancement, electromagnetic enhancement, surface defects of semiconductor, exciton Bohr radius were analysed.
