[21a-PA1-8] Nonelectrical poling behavious of FTC choromophores nonlinear optical
Keywords:nonlinear optical chromophores, nonelectrical poling
No electrically poling effects were investigated for phenylene vinylene thiophene vinylene bridge with dihydroxy ethyl amine and CF3 substituted 2-Dicyanomethylene-3-Cyano-4, 5, 5-trimethyl 2,5,-dihydrofuran.Our experimental results demonstrated that the polymethyl methacrylate thin films doped with the chromophores exhibited second harmonic generations just by thermally annealing even without applications of electric fields.
