ポリエチレンテレフタレート基板上に作製されたバナジルフタロシアニン薄膜の非線形光学特性

Abstract

Vanadyl-phthalocyanine (VOPc) thin films were prepared on Polyethylene-terephthalate (PET) substrate by a molecular beam epitaxy (MBE). Dependence of morphologies and nonlinear optical properties of the VOPc films on preparing conditions was investigated using UV/VIS spectroscopy and third harmonic generation measurements. VOPc films prepared on the substrate of different temperatures (60℃～120℃) showed two structures of a phase I and phase II. We suggested that the threshold temperature for structure changing from phase I to phase 11 existed at the vicinity of 80℃ and also indicated that the TH intensity of VOPc thin film having phase 11 was more larger than that having phase I.
