有機ガス処理されたKBr基板上のバナジルフタロシアニン膜の相遷移 Phase Transition of Vanadyl-phthalocyanine Film Prepared on KBr Treated in Organic Vapour
The vanadyl-phthalocyanine (VOPc) film prepared with MBE on the KBr substrate was treated in organic gas. The thickness of prepared film is 96 nm. The morphology of VOPc film was characterized with opticl absorption spectra in visible and infrared regions (VIS/UV) and SEM. The second and third hormonic generations (SHG and THG) of film was also measured by a Maker fringe method using a Nd-YAG laser. From these results, we clearly indicated that the phase transition of film occurred from a pseudomorphic epitaxy to an epitaxy and also showed that the nonlinear optical properties of VOPc film were improved with the phase transition.
