摘要:

制备了立方体、 直角立方体、 球形、 棒状、 中空状、 核壳状、 梭形、 多面体等8种不同形貌的普鲁士蓝纳米粒子, 利用扫描电子显微镜、 透射电子显微镜、 紫外-可见分光光度计等对纳米粒子进行了表征,考察了普鲁士蓝纳米粒子光热性能的影响因素. 结果表明, 普鲁士蓝纳米粒子的形貌与光热性能之间联系密切, 粒子形貌不同, 光热性能不同; 当外部实验条件一定时, 纳米粒子的形貌、 大小、 吸收横截面积、 尖锐化程度及密实程度等对其光热性能有很大的影响; 当纳米粒子形貌一定时, 外部因素如激光器的选择、 激光功率密度及纳米粒子的浓度等直接影响普鲁士蓝纳米粒子的光热性能; 在相同浓度下, 激光功率密度越大, 纳米粒子的升温效果越明显, 光热性能越好; 而激光功率密度不变时, 纳米粒子浓度越大, 其光热转换效率越高.

Abstract:

To clarify the factors that influence photothermal property, prussian blue nanoparticles(PB NPs) with different morphologies, including cube, rectangular cube, sphere, rod, hollow, core-shell, spindle and polyhedron, were synthesized and characterized by the scanning electron microscopy, X-ray diffraction and UV-Vis spectrophotometry. The results show that the morphologies of PB NPs were closely related to their photothermal property. And several factors, such as particle size, morphology, structure and the absorption cross-sectional area of particle, could make a huge difference in photothermal property under the same external experiment conditions. In addition, the experimental conditions, such as laser source, laser power density and the concentration of materials, could also play critical roles in photothermal property of PB NPs. Importantly, at the same concentration, the laser power density greatly affected the photothermal property of PB NPs. On the other hand, at the same laser power density, the higher concentration of PB NPs resulted in a better performance of photothermal property.
