Synthesis of Fast Curing, Water?Resistant and Photopolymerizable Glass for Recording of Holographic Structures by One? and Two?Photon Lithography

Advancements in hybrid sol-gel technology have provided a new class of holographic materials as photopolymerizable glasses. Recently, number photosensitive glass compositions with high dynamic range and spatial resolution been reported their excellent capability for volume holography has demonstrated. Nevertheless, challenges remain, particularly relation to the processing time environmental stability these materials, that strongly affect performance durability fabricated holograms. State-of-the-art glasses possess long curing times (few days) required achieve thick films, thus limiting industrial implementation this its commercial viability. This article presents novel, fast curing, water-resistant, (PHSG) applications. Due introducing an amine-based modifier increases condensation ability network, PHSG overcomes problem can readily produce (up few hundred micrometers) layers without cracking breaking. In addition, exhibits water-resistance, providing stable gratings up 400 h immersion water. finding moves next development stage renders attractive mass production optical elements use across wide outdoor
