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 II particles of VOPc are observed by a scanning electron microscope (SEM). The formation mechanism of VOPc nanoparticles in phase II is discussed in this paper.
