Abstract: The effects of ion implantation on the structure of nano-Si3N4 was studied by means of FT-IR, XPS and photoluminescence spectra. The energy level scheme and the energy structure of nano-Si3N4 were given. The results show that ion implantation makes free Si in the material change to SiNn(n=l, 2), and nano-Si3N4 possesses a quantum confinement effect, and its photoluminescence peak position and intensity are unstable.

Key words: quantum confinement, unstablity of photoluminescence, ion implantation, nano-Si3N4
