摘要

纳米粒子(NPs)由于其高表面体积比和零维限制而广泛应用于探测器,催化,光电子和医疗设备。然而,在创造新型纳米结构材料的过程中,解决环境问题是至关重要的。本文采用脉冲激光烧蚀法(PLAL)在70、90和130 mJ的能量下制备了不同尺寸的ZnO纳米粒子。利用扫描电镜、x射线能谱和透射电镜对合成的NPs进行了形貌和结构表征。采用zeta-size和zeta-potential来保证NPs的物理稳定性。紫外可见分光光度法测量显示,随着脉冲激光能量的增加,带隙出现蓝移,导致NPs尺寸减小。傅里叶变换红外光谱技术证实了ZnO NPs的形成。

Synthesis, characterization, and analysis of zinc oxide nanoparticles using varying pulsed laser ablation energies in liquid
Nanoparticles (NPs) find widespread applications in detectors, catalysis, optoelectronics, and medical devices, owing to their high surface-to-volume ratio and zero-dimensional confinement. However, addressing environmental concerns is crucial during the creation of novel nanostructured materials. Herein, ZnO NPs of different sizes were prepared via the pulsed laser ablation in liquid (PLAL) method at energies of 70, 90, and 130 mJ. The morphology and structural properties of the synthesized NPs were characterized by scanning electron microscopy, energy-dispersive X-ray spectrometry, and transmission electron microscopy. zeta-sizer and zeta-potential were used to ensure the physical stability of NPs. UV-Vis spectrophotometry measurement showed a blue shift in the band gaps with an increase in the pulsed laser energy leading to a decrease in the size of the NPs. Fourier-transform infrared spectroscopy technique confirmed the formation of ZnO NPs.

期刊介绍: Journal of Experimental Nanoscience, an international and multidisciplinary journal, provides a showcase for advances in the experimental sciences underlying nanotechnology and nanomaterials. The journal exists to bring together the most significant papers making original contributions to nanoscience in a range of fields including biology and biochemistry, physics, chemistry, chemical, electrical and mechanical engineering, materials, pharmaceuticals and medicine. The aim is to provide a forum in which cross fertilization between application areas, methodologies, disciplines, as well as academic and industrial researchers can take place and new developments can be encouraged.
