エピキタシー成長したバナジルフタロシアニン膜の非線形光学特性 Nonlinear Optical Properties of Vanadyl-Phthalocyanine Films Grown with Epitaxy
Vanadyl-phthalocyanine (VOPc) films were prepared on KBr substrate by MBE. They were characterized with RHEED, optical absorption spectra in visible and infrared regions (UV/VIS) and SEM. The thickness of prepared films is above 100 nm. The second and third harmonic generations (SHG and THG) of films were also measured by a Maker fringe method using a Nd·YAG laser. From these results, it was concluded that films are epitaxy films. We also estimated that the SH intensity of VOPc films are about 20 times higher than that of a Y cut quartz crystal and the third-order susceptibility χ<SUP>(3)</SUP> of VOPc film is about 3 times greater than the value reported recently by Fang et al.
