在球磨机中机械研磨ZnO粉末。这一过程被发现大大提高了它的蒸发能力。这种反常的蒸发行为是由研磨后材料的无序结构引起的，与研磨后材料表面积的增加无关。ZnO纳米线的合成通过蒸发这种研磨前体。纳米线与光滑和粗糙的表面存在于样品中，后者的形态占主导地位。纳米线的阴极射线发光光谱中以510 nm为中心的绿色发射带占主导地位。
ZnO powder was mechanically milled in a ball mill. This procedure was found to greatly increase its evaporation ability. The anomalous evaporation behaviour was caused by the disordered structure of the milled material and was not related to the increase in its surface area after milling. ZnO nanowires were synthesized by evaporation of this milled precursor. Nanowires with smooth and rough surfaces were present in the sample; the latter morphology was dominant. A green emission band centred at 510 nm was dominant in the cathodoluminescence spectrum of the nanowires.
