垂直氧化锌纳米线中的激射现象
The Lasing Action Observed in Aligned ZnO Nanowires
摘要
Abstract
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/cm2 can be clearly observed.关键词
