Abstract
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 emi
ssion was observed peaking at dark red, green and blue regions for the as g
rown and partially oxidized SiNW samples. The red PL emission is ascribed t
o the quantum confinement effect of the crystalline core of the SiNWs, whil
e the green and blue ones are attributed to the radiative recombination of
the defect centers in the amorphous silicon oxide layer surrounding the SiN
