化学气相沉积法制备β-Ga2O3纳米结构及其缺陷发光性质研究
Defects Luminescence Behavior of β-Ga2 O3Nanostructures Synthesized by Chemical Vapor Deposition
摘要
Abstract
β-Ga2 O3 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 spec-tra of the NWs and NBs, it is found that the UV and blue luminescence of β-Ga2 O3 NWs and NBs located at 374 and 459 nm, mainly due to radiative recombination emission of oxygen vacancies ( VO(Ⅰ) and VO(Ⅱ) ) .关键词
