有机膦酸锆形成可预测的椭偏厚度的热稳定表面多层。荧光和非线性光学性质的染料纳入这样的电影表示有组织的结构，但是，其他数据的地方限制的程度上获得的秩序。在这里，我们提出的证据收集到的IR，XPS和循环伏安法，锆膦酸盐多层膜是不完美的比以前认为，并包含在薄膜生长的初始阶段产生的缺陷。我们仍然认为过渡金属膦酸盐基质是有吸引力的constructingnovel光学材料，但在制造有源结构，它将是必要的，以弥补缺陷。目前正在评价这样做的方法。
Zirconium organophosphonates form thermally stable surface multilayers of predictable ellipsometric thickness. Fluorescence and nonlinear optical properties of dyes incorporated in such films indicate organized structures; however, other data place limits on the degree of order obtained. Here, we present evidence gleaned from IR, XPS, and cyclic voltammetry that Zr phosphonate multilayers are less perfect than previously thought and contain defects arising in the initial stages of film growth. We still consider the transition metal phosphonate matrix to be attractive for constructingnovel optical materials, but in fabricating active structures it will be necessary to compensate for defects. Approaches to doing so are under evaluation.
