Liquid light-emitting element, light-emitting device, method for making light-emitting device, and light-emitting body
Abstract:
A light-emitting device comprising a pair of baseplates respectively having surfaces facing each other, each surface having an electrode formed thereon, and a light-emitting layer sandwiched between the two baseplates. The light-emitting layer contains an ionic liquid and a light-emitting material dissolved in the ionic liquid. Since the light-emitting device is made without using any organic solvent, it is highly safe, does not deteriorate in emission characteristics, and requires a decreased number of constituent materials.
Abstract(Chinese):

一种发光器件，包括分别具有彼此面对的表面的一对基板，每个表面上形成有电极，以及夹在两个基板之间的发光层。 发光层含有溶解在离子液体中的离子液体和发光材料。 由于发光装置是在不使用任何有机溶剂的情况下制造的，因此其安全性高，不会劣化发光特性，并且需要减少构成材料的数量。
