The Effect of Argon Ion Implantation and Preanodization Argon Ion Implantation on Photoluminescence of Porous Silicon
Photoluminescence of Ar+ implanted porous silicon and porous structure of Ar+-implanted silicon (porous silicon by preanodization ion implantation) at energy of middle-energy (30keV) are investigated to gain insight into the photoluminescence properties and photoluminescence mechanism. The results show that the photoluminescence intensity of Ar+ implanted porous silicon was reduced, which was attributed to the removal of surface oxygen and creation of defects that act as nonradiative recombination; And whether samples were prepared by p-type or n-type silicon wafers, the photoluminescence intensity of porous structure of Ar+-implanted silicon was enhanced that we attribute these to the enhanced formation of porous silicon microstructure induced by ion implantation and oxygen-related defects were increased.
