| 研究開始時の研究の概要 |
The novel idea is to synthesize bi-metallic (Ln(III) and d-transition metal) assemblies with organic ligands, which will have possibility to incorporate three different properties (Non linear optical, emission and magnetic properties) originating from each center using thiocyanide as a bridge. In this way, by changing the organic ligand or d transition metal one can tune the coordination geometry of lanthanide ions to induce the improved magnetic and emission properties. Additionally, functionalization of the ligands can yield other effects like non linear activity.

| 研究実績の概要 |
I prepared three molecular compounds with the composition [DyxIIIY1-xIII(phen)2(μ-OH)2(H2O)2].[AuI(SCN)2]2.phen (x = 0 (DyAu), 0.1 (Dy0.1Y0.9Au), 0.02 (Dy0.02Y0.98Au); phen = 1,10-phenanthroline) containing lanthanide(III) ions (Ln3+) and bis(thiocyanato)gold(I) ions and solvents. The presence of two Au(I) atoms at a close distance make these assemblies attractive, which contain excimer-based emission properties and Au-Au vibrational features in the low-frequency (LF) region. The themometric ability utilizing Stokes and anti-Stokes Raman shift was charecterized. We also showed that this can be applied to detect the phase-transition of an unknown material. We also designed emission thermometer utilizing the luminescence of Dy(III) and Au(I) ions and compared it with Raman thermometer.
