Laser Powder Influence Tungsten Oxide Nanowire
Using different power laser radiation study tungsten oxide nanowires found that with increasing laser power (0.72mw ~ 20mw), the Raman spectra of tungsten oxide nanowire has significant changes, when the laser power Raman spectra of tungsten oxide nanowire is low the Raman signal also not strong. Peak shape and peak data will not change much. As the power increases, the Raman signal also increases. When the laser power is increase to certain strength, then tungsten oxide will react with oxygen become tungsten trioxide. At this time the tungsten trioxide is monoclinic phase.
When the laser powder drops to 3mw the Raman peaks has been unable to return to the peak, indicating that the oxidation process is irreversible. With the laser power is increased again, tungsten trioxide nanowire phase transition from monoclinic phase to β phase, has studying by the changing of laser power found the monoclinic phase of tungsten oxide change to the β phase so the this process is reversible. Laser powde has an impact on tungsten oxide nanowires, Keywords: tungsten oxide nanowires, laser power.
