采用纳米粒子辅助脉冲激光沉积法在氧气背景气体中制备了纳米结构的ZnO薄膜。采用脉冲激光沉积技术，在无催化剂的情况下，在加热到700 ℃左右的蓝宝石衬底上生长了平均直径约为300 nm、长度为6 μ m的ZnO纳米棒。在308 nm激发下，观察到纳米棒在带隙附近的强光致发光。还进行了羽流的瑞利散射诊断，揭示了纳米棒从羽流中形成的ZnO纳米颗粒生长并被输送到衬底上。
Nano-structured ZnO thin films were synthesized by the nanoparticle assisted pulsed-laser deposition in an oxygen background gas. Crystallized and c-axis oriented ZnO nanorods with a size of approximately 300 nm in average diameter and 6 mum in length were grown on sapphire substrates heated at approximately 700degreesC by the pulsed-laser deposition technique without any catalyst. Strong photoluminescence near the band-gap was observed from nanorods under excitation at 308 nm. The Rayleigh scattering diagnostics of the plume was also conducted, revealing that the nanorods grew from ZnO nanoparticles which formed in the plume and were transported onto the substrate.
