Laser action in ZnO nanoneedles selectively grown on silicon and plastic substrates
An ion-beam technique has been employed to fabricate nanoscale needlelike structures in ZnO thin films on silicon and plastic substrates at room temperature. The ZnO nanoneedles showed a single-crystalline wurtzite structure, the stem of which was around 100 nm in diameter. The sharp tips of the...

| description | An ion-beam technique has been employed to fabricate nanoscale needlelike structures in ZnO thin
films on silicon and plastic substrates at room temperature. The ZnO nanoneedles showed a
single-crystalline wurtzite structure, the stem of which was around 100 nm in diameter. The sharp
tips of the nanoneedles exhibited an apex angle of 20° as measured by transmission electron
microscopy. Room-temperature ultraviolet random lasing action was observed in the ZnO
nanoneedle arrays under 355 nm optical excitation. |
