Abstract
The photoluminescence (PL) properties of our silica wires were investigated with PL, PL excitation and PL decay. A high brightness photoluminescence band at 2.8Â eV with a shoulder around 3.0Â eV was observed in our silica wires. Two PL excitation bands for the 2.8Â eV emission were observed at 4.77 and 3.37Â eV. The 3.37Â eV excitation band is reported for the first time. The characteristic of the blue PL in our silica wires was different from that of the well-known 2.7Â eV PL in bulk silica material, suggesting a negation of previous attribution of blue emission in silica nanowires. The mechanism of the PL was also discussed.
