Paper Abstract

In this paper one novel conjugated enzothiazole derivative doped Polymethyl methacrylate C18H15N3SFe with D-π-A structures were synthesized to realize reverse saturable absorption (RSA) under femtosecond laser excitation resulting from two-photon absorption (TPA) and TPA-induced excited-state absorption (TPA−ESA). we describe the linear and nonlinear optical (NLO) properties of enzothiazole derivative doped Polymethyl methacrylate C18H15N3SFe. The nonlinear absorption of Polymethyl methacrylate can be enhanced by enzothiazole derivative doped. The Z-scan results revealed that C18H15N3SFe/PMMA showed RSA on the femtosecond time regions (532 nm). All the results indicate show that C18H15N3SFe /PMMA are promising candidates for future optoelectronic and RSA applications.
