首次展示了新开发的以聚乙烯醇缩丁醛树脂和菲醌分子为光敏掺杂剂的有机玻璃薄膜，这些薄膜被提出作为夹层安全玻璃的夹层。将菲醌-聚甲基丙烯酸甲酯注入到聚乙烯醇缩丁醛保护夹层中提供了记录全息介质在层中的均匀分布，并允许将整个表面光栅固定在夹层玻璃中。此外，在夹层玻璃的制造过程中，作为连接材料的聚乙烯醇缩丁醛的原始性能得到了保留。这允许在夹层玻璃烘烤后直接记录全息结构，从而减少由于温度升高而对栅格的破坏。菲醌-聚甲基丙烯酸甲酯-聚乙烯醇缩丁醛聚合物薄膜的衍射结构被密封在两块玻璃(所谓的夹层玻璃)之间，并由514 nm的Ar激光照射产生。记录在菲醌-聚甲基丙烯酸甲酯-聚乙烯醇缩丁醛薄膜中的高效固定和长期稳定的全息光栅能够产生带有嵌入的衍射元件的透明夹层玻璃，可用于例如汽车挡风玻璃的平视显示器或太阳能电池的全息聚光器。
The newly developed Plexiglas films containing polyvinyl butyral resins and phenanthrenequinone molecules as photosensitive dopant, which are proposed for the practical application as interlayer of laminated safety glass, are shown for the first time. The injection of the phenanthrenequinone–poly(methyl methacrylate) into the polyvinyl butyral protective interlayer provides a homogenous distribution of the recording holographic medium in the layer and allows fixing the entire surface grating in the laminated glass. In addition, the original properties of polyvinyl butyral as a connecting material were preserved during manufacturing of the laminated glass. This allows a recording of holographic structures directly after baking of the laminated glass, thus reducing the destruction of the gratings due to the elevated temperatures. The diffractive structures in phenanthrenequinone–poly(methyl methacrylate)–polyvinyl butyral polymeric layers with thicknesses of hundreds of microns are sealed between two panels of glass (so-called laminated glass) and are generated by illumination with an Argon-laser of 514nm. Efficiently fixed and long-term stable holographic gratings recorded in the phenanthrenequinone–poly(methyl methacrylate)–polyvinyl butyral layer enable to produce transparent laminated glass with inserted diffractive elements, which can be used e.g. for Head-up Displays in automobile windshields or as holographic light concentrators for solar cells.
