| 摘 要： | 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60 nm.对相II型酞菁氧钒纳米颗粒的形成机理进行了讨论.

| Abstract: | The polycrystalline vanadyl phthalocyanine (VOPc) nanoparticles in phase I and phase II have been fabricated by laser ablation in aqueous solution without or with a kind of nonionic surfactants respectively. X ray diffraction patterns, UV Vis absorption spectroscopy and Fourier transform infrared(FT IR) spectroscopy have been used to characterize the crystalline structures in VOPc nanoparticles. About 100 nm sized in phase I and 60 nm sized in phase IIparticles of VOPc are observed by a scanning electron microscope (SEM). The formation mechanism of VOPc nanoparticles in phase II is discussed in this paper. |
