Structural Control and Optical Properties of Spiropyran LB Films (II) -Preparation Condition and Nonlinear Optical Properties-

摘要

Spiropyran (SP18 and SP1822) films were prepared by the Langmuir Blodgett method, and the relation among the preparation condition, the film structure and the optical properties such as the UV-visible absorption and the third-order nonlinearity were investigated. The AFM images showed that the surfaces of spiropyran LB films prepared by adding proper amount of archidic acid and n-oct adecane were smooth, indicating that the structures of these films were successfully controlled.
