在这项工作中，我们提出了一种定量的方法来确定金属氧化物纳米粒子（NP）的浓度在液体中通过激光烧蚀合成。该案例研究是用二氧化钛纳米颗粒（TiO 2 NP）进行的，该纳米颗粒是通过在水中激光烧蚀Ti靶合成的。合成后，用UV-Vis光谱分析胶体溶液。同时，用光学显微镜评价消融后钛靶上残留的凹坑，以确定消融材料的体积。使用SEM显微镜来确定TiO 2 NP尺寸分布。结果发现，合成的TiO 2 NP遵循对数正态分布，在约64 nm处具有最大值。根据烧蚀材料的体积和NP尺寸分布，在大部分烧蚀材料被消耗以形成纳米颗粒的假设下，可以确定纳米颗粒的浓度。所提出的方法进行了验证，通过比较所计算的浓度的值从比尔-朗伯定律使用米氏散射理论的NP截面计算。
In this work, we present a quantitative method for determining the concentration of metal oxide nanoparticles (NP) synthesized by laser ablation in liquid. The case study was performed with titanium dioxide nanoparticles (TiO2 NP), which were synthesized by laser ablation of a Ti target in water. After synthesis, a colloidal solution was analyzed with UV-Vis spectroscopy. At the same time, the craters that remained on the Ti target after ablation were evaluated with an optical microscope to determine the volume of the ablated material. SEM microscopy was used to determine the TiO2 NP size distribution. It was found that synthesized TiO2 NP followed a Log-Normal diameter distribution with a maximum at about 64 nm. From the volume of ablated material and NP size distribution, under the assumption that most of the ablated material is consumed to form nanoparticles, a concentration of nanoparticles can be determined. The proposed method is verified by comparing the calculated concentrations to the values obtained from the Beer–Lambert law using the Mie scattering theory for the NP cross-section calculation.
