通过水热的方法以退火0.5 h的ZnO薄膜作为籽晶
得到垂直的ZnO纳米线。在 X射线衍射谱中
除了Si的(400)衍射峰以外
只观察到了ZnO的(002)衍射峰。 室温光致发光谱中出现了强的紫外发射峰
同时也伴随着弱的缺陷相关的发射。这些数据表明垂直的ZnO纳米线序列有着较好的晶体质量。同时
通过光泵浦也观察到了ZnO纳米线中的激光发射。 当激发功率密度超过阈值且进一步增加时
出现了多模发射峰
其积分强度随着激发功率密度的增大呈非线性的增长
并且在96 kWcm

处能清晰地观察到从自发发射到激射的转变。
Aligned ZnO nanowires (NWs) were obtained by hydrothermal method using annealed ZnO film as seed layer.Besides Si(400)
only ZnO(002) diffraction peak was observed in X-ray diffraction(XRD) pattern. The lasing emissions were observed in optically pumped aligned ZnO NWs. Multi-mode emission peaks emerged when the excitation power density exceed the threshold.The integrated intensity of the spectra increases nonlinearly with the excitation power density
and the transition point from the spontaneous emission to lasing at about 96 kW/cm

can be clearly observed.
