摘要

与明亮光源(如激光器)一起应用的光学传感器通常必须通过使用光学限制器来保护其免受破坏性光暴露水平的影响。光学限制器材料的主要目标是:(1)在高光照水平下选择性地阻挡感兴趣的频率,在低光照水平下表现出高的光学频率透射率,以便制造透明但具有保护作用的窗口;(2)暴露在强光下反应时间快。光学透明双光子活性聚合物纳米复合材料为设计具有动态可切换限制特性的材料提供了新的机会,其中嵌入颗粒填料的散射强度可以通过聚合物宿主介质的非线性吸收来动态调制。在第一部分中,本文将介绍通过聚合物功能化方法合成与有机溶剂指数匹配的二氧化硅纳米颗粒的最新结果。有效介质理论将为预测与包埋溶剂指数匹配的聚合物接枝成分提供有价值的工具,从而显著降低颗粒分散剂的线性散射截面。本论文的第二部分将介绍双光子活性染料(TPA)溶剂和溶液中粒子色散的线性和非线性光学性质的初步结果。对于TPA染料和指数匹配的颗粒填料的混合溶液,观察到极限效率增加,而发现整齐的颗粒是TPA无活性的。

Design and fabrication strategies for high transparency polymer nanocomposites with dynamic tunable optical response
Optical sensors that are applied in conjunction with bright optical sources such as lasers typically have to be protected from damaging light exposure levels by the use of optical limiters. The principal aims for optical limiter materials are: (1) to block selectively the frequency of interest at high light levels and – at low light levels – exhibit high transmittance of optical frequencies in order to enable the fabrication of transparent yet protective windows; (2) a rapid response time when exposed to high light levels. Novel opportunities for the design of materials with dynamic switchable limiting properties are provided by optically transparent two-photon active polymer nanocomposites materials in which the scattering strength of embedded particle fillers can be dynamically modulated by the nonlinear absorption of a polymer host medium. In a first part this contribution will present recent results on the synthesis of silica nanoparticles that are index-matched to organic solvents by means of polymer functionalization. Effective medium theory will be shown to provide a valuable tool in predicting polymer-graft compositions that are index-matched to the embedding solvent thus resulting in dramatically reduced linear scattering cross section of the particle dispersant. The second part of this contribution will present preliminary results on the linear and nonlinear optical properties of particle dispersions in both solvent and solutions of two-photon active (TPA) dyes. For mixed solutions of TPA-dyes and index-matched particle fillers an increased limiting efficiency is observed while neat particles are found to be TPA inactive.
