We have established a novel molecular design concept of Eu(III) complexes for enhancing red photoluminescence intensity and solubility. Many Eu(III) complexes have been developed along this concept. We implemented them in LED devices and succeeded in obtaining large emission intensity with much lower concentrations compared with a KSF phosphor.
