Preparation, characterization, growing process and nonlinear optical property of large vanadyl-phthalocyanine single crystal

Vanadyl-phthalocyanine (VOPc) single crystals were prepared on KBr substrat e by molecular Learn epitaxy (MBE). Their maximum size is 13 x 8 x 0.16 mu m(3). The morphology of the VOPc single crystal was investigated from the r esults uf UV/VIS spectra and RHEED. They suggest that the VOPc single cryst al mag be grown with pseudomorphic layers. The growing process was expained by Volmer-Weber model. The third order nonlinear optical property of VOPc single crystal was measured with Maker fringe method. The value of the thir d order optical susceptibility (chi((3))) of VOPc single crystal was estima ted to Le about 10(-9) esu from the result of Maker fringe.
