在水溶液中利用激光消融制备了酞菁氧钒(VOPc)相I型纳米颗粒,在加入一种非离子型表面活性剂的情况下通过激光消融制备得到了其相II型纳米颗粒.X射线衍射(XRD)、紫外可见吸收光谱(UV-Vis)和傅立叶变换红外光谱(FT-IR)表征了其纳米颗粒中的晶体结构.扫描电子显微镜(SEM)观察显示相I和相II型酞菁氧钒纳米颗粒的直径分别约为100和60nm.对相II型酞菁氧钒纳米颗粒的形成机理进行了讨论.
The phase II nanoparticles of vanadyl phthalocyanine (VOPc) phase were prepared by laser ablation in aqueous solution, and their phase II nanoparticles were prepared by laser ablation with addition of a nonionic surfactant. X-ray diffraction XRD, UV-Vis and Fourier Transform Infrared Spectroscopy (FT-IR) were used to characterize the crystal structure of the nanoparticles. Scanning electron microscopy (SEM) observation showed that Phase I and Phase II phthalocyanine The diameters of the vanadium nanoparticles are about 100 and 60 nm, respectively. The formation mechanism of phase II vanadyl phthalocyanine nanoparticles is discussed.
