将在溶液中表现出优良非线性光学和光限幅性能的铟酞菁及其二聚物嵌入到非光学活性的聚甲基丙烯酸甲酯(PMMA)中,用传统的旋转涂膜法制备得到具有较高光学质量的复合物薄膜,用开孔Z-扫描方法在532nm处研究了复合物薄膜材料的线性光学和非线性光学性能.结果表明,无论是铟酞菁单体还是轴向氧桥联的铟酞菁二聚物,其PMMA复合材料的光限幅性能均显著优于相应的酞菁分子在溶液中的光限幅性能.
Indium phthalocyanine and its dimers, which exhibit excellent non-linear optical and optical limiting properties in solution, are embedded in non-optically active polymethylmethacrylate (PMMA) and are prepared by conventional spin-coating methods with The optical and nonlinear optical properties of the composite films were investigated by an aperture Z-scanning method at 532 nm with higher optical quality.The results show that both the indium phthalocyanine monomer and the axial oxygen bridge Of indium phthalocyanine dimer, the optical limiting properties of the PMMA composites are significantly better than those of the corresponding phthalocyanine molecules in solution.
