| titleOfInvention | Surface modification process for improving luminance and dispersity of porous silicon |
| abstract | The invention discloses a surface modification process for improving luminance and dispersity of porous silicon. By adopting a method that chemical corrosion is combined with electrochemical corrosion, porous silicon of tidy pore structures can be prepared in a large area, subsequently the porous silicon is subjected to surface modification by using olefin and olefine acid, and Si-C bonds are introduced into the surfaces of silicon grains. The photoluminescence intensity of grains of the modified porous silicon is remarkably improved when being compared with that of the grains of porous silicon which is not subjected to surface modification; and meanwhile the luminance stability of the silicon grains in polar and non-polar solvents is greatly improved, and the phenomenon that the luminous intensity is attenuated along with the time extension is effectively reduced; and in addition, the dispersing property of the silicon grains wrapping olefine acid molecules in polar solvents is good. The surface modification process is simple, convenient to operate and applicable to production in a large scale, and has a good industrial application prospect. |
