摘要: The type of donor used is found to influence greatly the optical nonlinearities iodine charge-transfer (CT) complexes in solutions for several solvents. magnitude and sign changes nonlinear absorption CT different solvents as donors are observed, which implies transition from saturable reverse absorption. Compared with C60 toluene, toluene benzene demonstrate larger Meanwhile, flexible alteration easily obtained by adjusting mixture ratio solvents, yielding a prospective means constructing medium large coefficient.
