Abstract
Soft luminescent materials resulting from the introduction of rare earth compounds to ionic liquids favorably combine the properties of ionic liquids with unique optical properties of rare earth compounds such as sharp emission band, long decay time of the excited state, and the tunable emission color over the entire spectral range of interest from UV to infrared spectral region. This chapter summarizes the progress ever made in such kind of soft luminescent materials, especially those that have been made in our research group. Our emphasis is put on the preparation strategies for the soft luminescent materials, the luminescent ionogels prepared from the immobilization of rare earth-containing ionic liquids by organosilica and polymers, and the unexpected luminescent enhancement of Eu3+-β-diketonate complexes hosted in zeolite L nanocrystals and nanoclay upon addition of ionic liquid bearing bulky triethoxysilane groups in water.
