Figure 5From: Carbon-assisted growth and high visible-light optical reflectivity of amorphous silicon oxynitride nanowires The optical reflectivity and PL spectra of Si-O-N nanowires. (a) Reflectivity of Si-O-N nanowire mat and its comparison with literature data of human milk tooth and Cyphochilus beetle scale [17]. (b) Room temperature PL spectra of Si-O-N nanowires, using a 258-nm line of a Xe lamp as the excitation.Back to article page
