Abstract
We report the new fluorescent polymerizable imidazolium-based ionic liquids for photonics application. We investigate two approaches: one ionic liquid (IL) contains the active fluorescein dianion as an intrinsic part of the polymerizable ionic liquid structure. The second liquid is based on the mixture of polymerizable ionic liquid with optically active europium(III) nitrate hydrate. We demonstrate the polymerization abilities of both liquids by means of electron beam in vacuum conditions. Furthermore, we measure the light emission properties of liquid and polymerized structures. The results reveal that IL with europium(III) nitrate hydrate yields emission spectrum with Eu3+ bands not only as a liquid but also as a polymerized solid microstructure, which is important for its application in active photonics components.
