摘要：

GaSe and Si nanowires (SiNWs) were synthesized by physical evaporation. The photoluminescence (PL) properties of the Si nanowires were investigated in correlation with the diameter of the crystalline core. Intensive light emission was observed peaking at dark red, green and blue regions for the as grown and partially oxidized SiNW samples. The red PL emission is ascribed to the quantum confinement effect of the crystalline core of the SiNWs, while the green and blue ones are attributed to the radiative recombination of the defect centers in the amorphous silicon oxide layer surrounding the SiNWs.
