之字形β-Ga_2O_3纳米材料的合成和表征

Synthesis and Characterization of Zigzag-shaped β-Ga_2O_3 Nanomaterials

采用溶剂热的方法,以NaN3和GaCl3做反应物,在二甲苯做溶剂的条件下,成功的合成了之字形β-Ga2O3纳米材料。利用XRD,TEM,SAED,EDS,HRTEM,PL和模型分别对之字形β-Ga2O3纳米材料的形貌和结构进行了分析。结果表明,之字形β-Ga2O3纳米材料是良好的单晶,沿着[10 3]方向子自堆垛生长。另外光致发光光谱也显示之字形β-Ga2O3纳米材料在370 nm处有很强的发射峰,并且发生了几十纳米的蓝移。

Zigzag-shaped β-Ga2O3 Nanomaterial was successfully composed with solvothermal methods.GaCl3,NaN3 was used as the reactants,and dimethylbenzene was used as solvent.The morphology and structure of these nano-materials were analyzed by XRD,TEM,SAED,HRTEM,PL and model.The results showed that this zigzag-shaped β-Ga2O3 Nanomaterial was a good single crystal growing with[10 3^-] by self-stowing.Besides,the optical property of β-Ga2O3 was observed in the photoluminescence（PL） spectra,which showed that this nanomaterial emits strong luminescence at 370 nm,and dozens of nanometer blue-shift occurred.
