Visible photoluminescence in ion beam mixed SiO2/Si/SiO2 layers
Visible photoluminescence from silicon nanocrystals embedded in SiO2 matrix by ion beam mixing was investigated. Photoluminescence spectra of ion beam mixed SiO2/Si/SiO2 films excited by an Ar-laser (457.9 nm) showed more intense luminescence with a peak centered at 720 nm than that prepared by the conventional ion implantation method. The formation of nanocrystals in SiO2 matrix was confirmed by cross-sectional high resolution transmission electron microscopy. The red luminescence is attributed to the silicon nanocrystals produced by ion beam mixing.
