【摘要】 采用溶胶-凝胶(Sol-gel)旋涂法在石英衬底上制备Mg掺杂ZnO纳米薄膜,室温下利用X射线衍射(XRD)、光致发光谱(PL)等手段分析所得ZnMgO合金薄膜的晶体结构和发光特性.结果表明:在0.1<x<0.37范围内,合金薄膜仍然保持氧化锌六角纤锌矿结构,(002)衍射峰位随x的增大向大角度方向移动.室温光致发光谱表明:ZnMgO合金薄膜PL谱由较弱的紫外发射带和较强的可见发射带组成,且随着Mg含量的增加紫外发射峰位发生蓝移,同时可见发射增强.更多还原

【Abstract】 The method of Sol-Gel is adopted to produce the Zn1-xMgxO(x=0.1,0.2,0.3,0.37) alloying thin film.XRD shows: when the value of x is between 0.1 and 0.37,the alloying thin film remains the structure of hexagonal wurtzite and the angle of(002) diffraction peak becomes bigger as the value of X increases.The photoluminescene spectra at room temperature shows that the PL spectra of the alloying thin film is composed of the weaker UV emission band and stronger visible band,and UV emission peak will have the blue shift with the content of Mg increasing and the visible emission strengthened.更多还原
