中文摘要：

锌氧化物六角形的管状的晶体被直接微波没有任何金属催化剂或运输代理人，在 5 min 以内从 ZnO 粉末加热综合。ZnO 原始资料在围场从高温度的地区被蒸发，并且晶体在处于一个适当条件的自我来源底层上是成年的。在高温度的地区形成的 ZnO 蒸汽能在位于低温度的地区形成晶体的粉末上扔并且成长。扫描电子显微镜学 SEM 表明这些产品在长度是有在直径和 250 m 的 80 ~ rn 的六角形的试管晶体，有井 faceted 结束和方面表面。可能的生长机制和水晶的 ZnO 六角形的试管的形成上的反应温度的影响被介绍。光致发光 PL 在房间温度展出强壮的紫外排放，显示在短波的潜在的应用轻射出的 photonic 设备。

英文摘要：

Zinc oxide hexagonal tubular crystals were synthesized by direct microwave heating from ZnO powders within 5 min without any metal catalysts or transport agents. ZnO source materials were evaporated from the high-temperature zone in an enclosure, and crystals were grown on the self-source substrate in an appropriate condition. The ZnO vapor formed in the high-temperature zone can deposit and grow on the powders located in the low-temperature zone to form crystals. The scanning electron microscopy （SEM） reveals that these products are hexagonal tube crystals with 80 ~rn in diameter and 250 μm in length, having a well faceted end and side surface. A possible growth mechanism and the influence of reaction temperature on the formation of crystalline ZnO hexagonal tubes were presented. The photoluminescence （PL） exhibits strong ultraviolet emission at room temperature, indicating the potential applications in short-wave light-emitting photonic devices.
