Outline of Final Research Achievements

In order to explore novel photo-functions of gadolinium(III) complexes, we have focused on the design and synthesis of new gadolinium(III) complexes. As a result, it was found that a gadolinium(III) complex with phenyl units shows room temperature phosphorescence in the crystalline state. We also clarified that the luminescence color can be controlled by doping trace amounts of organic compound at the time of crystal preparation. In addition, we have succeeded in developing new luminescent lanthanide(III) complexes with excellent oxygen response function by using the findings of photo-physical properties of newly synthesized gadolinium(III) complexes.
