摘要

利用化学气相沉积法（CVD），在不同压强下分别得到-Ga

纳米线（NWs）和纳米带（NBs）。研究结果表明，获得的NWs与NBs均为单斜结构的-Ga

，且NWs结晶质量优于NBs。在阴极射线发光（CL）光谱中，发现NWs与NBs在近紫外和蓝光波段有较强的发光。对比NWs与NBs的CL光谱，推断-Ga

在374 nm和459 nm的近紫外和蓝色发光峰分别来自于Ⅰ型和Ⅱ型氧空位（V

Abstract

-Ga

nanowires (NWs) and nanoribbons (NBs) were synthesized under different gas flow rates

via

chemical vapor deposition (CVD) method. The results show that the NWs and NBs are monoclinic structure. NWs has higher crystal quality than NBs. The cathode luminescence (CL) spectra show that the NWs and NBs have strong UV-blue emission band. By comparing the CL spectra of the NWs and NBs

it is found that the UV and blue luminescence of -Ga

NWs and NBs located at 374 and 459 nm

mainly due to radiative recombination emission of oxygen vacancies (V

O(Ⅰ)

and V
