摘要

在本研究中，我们在波长为532nm、两种能量为360和800mJ的液体中通过激光烧蚀合成了Pd NPs，并研究了它们之间的差异。在XRD衍射中，晶体尺寸分别增加了21.7和24.21 nm，而在TEM和SEM中，Pd纳米球的形貌分别为平均颗粒19.4和27.5 nm，紫外-可见光谱显示出294和309 nm的最高吸收峰，随着激光能量的增加，能带隙分别减小了4.04和3.75 eV。这些检查适用于光催化。

Studying the Photocatalytic Characteristics of Pd Nanoparticles Created by Second Harmonic Laser Ablation

In this study, we synthesize Pd NPs by laser ablation in liquid with a wavelength of 532 nm and two energies of 360 and 800 mJ, and study the difference between them. In XRD diffraction, the crystal size increases by 21.7 and 24.21 nm, while the morphology of the Pd nanospherical in the TEM and SEM see average particles 19.4 and 27.5 nm, UV–vis spectroscopy showed the highest peak of absorbance 294 and 309 nm with energy band gap decreases 4.04 and 3.75 eV with increase laser energy. The examinations were suitable for photocatalytic.

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
