| 研究実績の概要 |
I have prepared several pseudohalide containing complexes with general molecular formula [YbIII(TPPO)3(NCE)3] (E = S, YbS; Se, YbSe, TPPO = triphenylphosphine oxide), [NdIII(phen)3(NCX)3]-0.3EtOH (X = S, 1-S; Se, 1-Se), and [REIII(phen)2(μ-OH)2(H2O)2][AuI(SCN)2]2.phen.0.5MeCN.0.5H2O [REIII = Gd (GdAu2), Y (YAu2)] and [REIII(bpdo)4][AuI(SCN)2]3.MeCN [REIII = Gd (GdAu3), Y (YAu3)]. Compounds YbS and YbSe exhibit strong second harmonic generation behaviour and temperature-dependent emission. Similarly, 1-S and 1-Se have absorption below 1 THz due to their vibrational and have near-infrared emission. Compounds GdAu2, YAu2, GdAu3, and YAu3 have Au-Au stretching vibrations seen in the Raman scattering. They also exhibit strong luminescence originating from Au(I) centres.

| 今後の研究の推進方策 |
In the last year's research, I prepared two compounds with the general formula [REIII(phen)2(μ -OH)2(H2O)2].[AuI(SCN)2]2.phen.0.5MeCN.0.5H2O [REIII = Gd (GdAu2), Y (YAu2)]. They reveal emission properties and Raman scattering related to the Au(I) centres. We will utilize this system to introduce Dy(III) ions. The Dy(III) containing compound is supposed to reveal emission and magnetic properties. Additionally, we plan to investigate its Raman thermometric behaviour as they have sharp Raman scattering in the low frequency region. Further, we will compare the thermometric sensitivity of Raman and emission spectroscopy. Further, we will plan to investigate the application of such a Raman thermometer to predict the phase transition temperature of unknown materials.
