A highly efficient luminescent material is produced from a 2,2′-bipyridine-lanthinide-ion coordination complex. The authors describe how this coordination complex can be stabilized by ethylene glycol oligomers. The material, obtained by simple mixing of the components, emits blue, green, and red photoluminescence by single near-UV excitation. Additionally, the complex can be mixed with silica through a sol-gel process, producing transparent soft solids that preserve all photophysical characteristics of the original liquid mixture. These materials may find applications in electroluminescent displays, lasers, or high-density optical storage.
