Abstract

Abstract: Covalent anchoring functional molecule to the silicon nanowire surface is one of the important strategy to obtain novel nanomaterials for silicon nanodevice.But a serious problem for this surface modified is the uncontrollably oxide of the surface of silicon nanowire in the modification process.Therefore,it is highly desired to find a mild method for the modification of silicon nanowires.In this paper,we covalently attached pyrene molecules onto the silicon nanowires’ surface through forming Si—O—C bond via reaction of Hydroxyl-(from the functional molecule) with Si—H(on the silicon nanowire surface).The product was characterized by ATR-FTIR;in addition,its fluorescence behavior was also investigated.

Key words: silicon, nanowires, pyrene, surface modification
