| Outline of Final Research Achievements |
Rare earth complexes were dispersed in self-assembly organogels to develop lasing materials including strong emitters with high emission quantum yield, Φ. In the present study we synthesized Ce complexes that emit in the violet - blue regions, which is not achieved by conventional Eu or Tb complexes. Ce complexes have an advantage of using 4f-5d transitions that cover the blue emissions. For Eu complexes, on the other hand, we update Φ = 46% in this study whereas Φ = 22% in the previous works. The heavy atoms introduced in the ligands hinder the path to the intramolecular vibrational process, which contributes to the efficient Φ value.
