Abstract

By employing the laser marker fast ablation technique in water, combined with the innovative inclusion of sonication, we successfully developed Ti-based nanoparticles with improved characteristics. sonication increased the nanoparticle concentration in the colloid, reduced nanoparticle size, and also narrowed size distribution. Our findings also provide valuable insights into the influence of laser parameters, such as wavelength and fluence, on nanoparticle properties. UV laser led to small nanoparticles compared with 1064 nm laser. Additionally, high laser fluence appeared to increase the ablated particle size until a plateau fluence at 28.5 J/cm; at 38 J/cm, the particle size decreased. Notably, all synthesized particles exhibited a regular spherical shape, as confirmed by energy dispersive X-ray spectroscopy (EDS) mapping, which also indicated that the majority of Ti-based particles were in an oxidized state. Additionally, the presence of rutile TiO in the particles was further confirmed by X-ray diffraction (XRD) analysis. Ceria doping Titania nanoparticles was also attempted.

摘要

通过采用激光标记在水中的快速烧蚀技术，并结合创新的超声处理，我们成功开发出了具有改进特性的钛基纳米颗粒。超声处理提高了胶体中纳米颗粒的浓度，减小了纳米颗粒的尺寸，还使尺寸分布变窄。我们的研究结果还为激光参数（如波长和能量密度）对纳米颗粒性能的影响提供了有价值的见解。与1064纳米激光相比，紫外激光产生的纳米颗粒较小。此外，高激光能量密度似乎会增加烧蚀颗粒的尺寸，直到在28.5焦每平方厘米时达到一个稳定的能量密度；在38焦每平方厘米时，颗粒尺寸减小。值得注意的是，所有合成颗粒均呈现规则的球形，能量色散X射线光谱（EDS）映射证实了这一点，该映射还表明大多数钛基颗粒处于氧化状态。此外，通过X射线衍射（XRD）分析进一步证实了颗粒中存在金红石型二氧化钛。还尝试了二氧化铈掺杂二氧化钛纳米颗粒。
