Silver nanowires of diameter ~ 5 nm were grown within thick films (0.6 µm thickness) of sol–gel-derived silica-based glasses of composition xAg2O(1 − x)SiO2; x having values of 30 and 40, respectively, by an electrodeposition method. By applying suitable voltage pulses to the composites, interrupted silver nanowires were produced with lengths having values in the range 4000–5000 nm. The samples exhibited...
