在氧化铟锡（ITO）/酞菁铜（CuPc）和ITO/并五苯的界面上观察到了光学二次谐波（SHG）的相移。考虑了由于样品的菲涅耳因子引起的相位校正。ITO/并五苯界面、ITO/CuPc界面的二次谐波电场相位与裸衬底ITO的二次谐波电场相位相差160°，而ITO/CuPc界面的二次谐波电场相位相差140°。
We observed phase shift in optical second harmonic generation (SHG) from interfaces of indium tin oxide (ITO)/copper phthalocyanine (CuPc) and ITO/pentacene. Phase correction due to Fresnel factors of the sample was taken into account. The phase of SHG electric field at the ITO/pentacene interface,ϕinterfacewith respect to the phase of SHG of bare substrate ITO was 160°, while the interface of ITO/CuPc had a phase of 140°.
