摘要

The microstructure, optical property and magnetism of nitrogen ion-implanted SiO_ 2 were studied. The nitrogen incorporation into SiO_ 2 was confirmed by means of x-ray photoelectron spectra and a Fourier-transform infrared absorption spectrum. The bond angle of SiOSi is decreased by nitrogen implantation. The absorption in the ultraviolet region is enhanced, which may be due to the band gap narrowing effect. Room-temperature ferromagnetic-like behavior is obtained in the nitrogen-implanted sample with a nominal dose of 1×10~ (18)ionscm~ 2.
