| 中文摘要 | The third-order nonlinear optical properties of a Keplerate-type polyoxometalate (NH4)(18)[(Bu4N](24)[Mo132O372(H2O)(72)(CH3COO)(30)]a <...ca.7NH(4)CH(3)COOa <...ca.173H(2)O (denoted Bu4N-{Mo-132}) in solution and in films of poly(methylmethacrylate) (denoted PMMA) matrix have been studied by the Z-scan method at 532 nm with a pulse duration of 20 ps. Experimental results show that both the solution and the solid films of Bu4N-{Mo-132} have nonlinear self-defocusing effects and notable nonlinear reverse saturable absorption. Embedding Bu4N-{Mo-132} as inclusion into PMMA host significantly improves the nonlinear absorption coefficient beta, while it reduces the nonlinear refractive coefficient as a result of the higher concentration of Bu4N-{Mo-132} in PMMA matrix than in solution. The magnitude of beta for solid-state Bu4N-{Mo-132} in films increases with the increasing amount of incorporated Bu4N-{Mo-132}, while the third-order nonlinear refractive index n (2) decreases. Experimental results prove the high stability of Bu4N-{Mo-132} in PMMA films in inorganic acidic and basic solutions. These studies indicate that Bu4N-{Mo-132} in thin solid films of PMMA are potential candidates for fabricating nonlinear optical devices. |
