Outline of Final Research Achievements

Ultimate goal of this study was preparation of a photonic material to convert photon energy by use of heteronuclear lanthanide cluster complex. For this purpose, we used thiacalix[4]arene (TCAS) which form the complex Tb3-xYbxTCAS2 (x = 1,2) with Tb and Yb. In the complex, the Tb to Yb energy transfer efficiency was high. Also, they were separated by electrophoresis and prepared by stepwise manner. Luminescent material was prepared by doping phosphonium salt of Tb3TCAS2 in a polymer, PMMA, showing that de-activation was suppressed. These outcomes are basic but essential to prepare photonic material by doping Tb3-xYbxTCAS2 (x = 1 or 2) into PMMA.
