以十六烷基三甲基溴化铵水溶液为介质，采用1064 nm的纳秒脉冲Nd：YAG激光器，通过脉冲激光烧蚀铜板制备了氧化铜纳米材料。采用紫外-可见吸收光谱、X射线衍射（XRD）和光致发光（PL）光谱对合成的纳米材料进行了表征。XRD表征证实了氧化铜纳米材料的形成。吸收光谱和荧光光谱的表征表明，合成的纳米材料具有较宽的带隙。并对纳米粒子的合成机理和发光机理进行了讨论。
Copper oxide nanomaterial is synthesized by pulsed laser ablation of copper plate in aqueous medium of cetyltrimethyl ammonium bromide using 1064 nm of nanosecond pulsed Nd:YAG laser. The synthesized nanomaterial is characterized by UV-VIS absorption, X-ray diffraction (XRD) and photoluminescence (PL) spectroscopic techniques. XRD characterization confirms the formation of copper oxide nanomaterial. The absorption and PL characterization shows that the synthesized nanomaterial has wide band gap. Mechanisms of nanoparticles synthesis and PL are also discussed.
