摘　　要：采用溶胶凝胶法在石英衬底上沉积ZnO纳米薄膜作为籽晶层,通过水热法在ZnO籽晶层上生长ZnO纳米棒阵列.结果表明:当先驱物物质的量浓度较低时,ZnO纳米棒方向性较弱;当先驱物物质的量浓度较高时,ZnO纳米棒呈现规则的方向性.ZnO纳米棒在390nm附近出现高强度的紫外发光,且发光强度随先驱物物质的量浓度的增大而增强.The sol-gel method was adopted to deposit a nano-size ZnO layer on a quartz substrate and it was taken as the seed crystal layer, and then, the ZnO nano-rod arrays were made to grow on the seed crystal layer with hydro-thermal method. The result showed that： the directionality of nano-rods would be weaker if the precursor concentration was lower; in contrast, the nano-rods would exhibit regular directionality when the precursor concentration was higher. High intensity of ultraviolet luminescence would take place near 390 tim, nano-particle and the intensity would increase with the precursor concentration.
