Abstract
By using the femtosecond optically heterodyned optical Kerr effect at 647.0 nm we have measured the magnitudes and signs of the real components of third-order nonlinearity of organometallic compounds films of C60M2 fabricated through a series of reactions of C60 anions with some inorganic compound in solution phase and physical jet deposition technique. We find there is an enhancement of the real components of third-order optical nonlinearities of C60M2 films compared to that of pristine C60 film, which can be attributed to the charge transfer from metal atoms to C60 molecules. The signs of the real components of third-order optical nonlinearity of C60 and C60$M(subscript 2 films are negative. We also find the disposition temperature will affect third-order optical nonlinearities of C60M2 films.
