Abstract:

以氢氧化钠和氢氧化锂作为助熔剂,采用常压混合碱液法成功生长了各种形貌的ZnO晶体。以Bravais-Friedel-Donnay-Harker法则为指导,获得了ZnO晶体的几种理论结构晶形;在考虑晶体内部结构和生长实验中外部生长条件下,得到了晶体的实验晶形。采用光学显微镜、扫描电子显微镜和原子力显微镜对六方片状晶体的表面形貌进行了研究。结果表明晶体的理论结构晶形和实验晶形吻合良好;晶体具有二维螺旋生长的机制。此外,晶体在325nm光激发的室温光致发光光谱显示,在380nm处存在1个强的紫外发射峰和位于652nm处的弱且窄的红光发射峰,说明生长的六方片状ZnO晶体结晶质量优良。
