We performed spectroscopic investigations of a novel tris(1,3-bis(1,3-dimethyl-1H-pyrazol-4-yl)propane-1,3-dionato)(1,10-phenanthroline) holmium (III) complex. It was demonstrated that bonding the corresponding ligand environment to Ho3+ results in sensitization of the luminescence of the complex. The luminescence decay of the complex exhibits a biexponential behaviour. The short-lived component is
我们对新的三(1,3-双(1,3-二甲基-1 H-
吡唑-4-基)
丙烷-1,3-去离子基)(1,10-
菲咯啉)(III)进行了光谱研究。已经证明将相应的
配体环境结合到Ho 3+导致复合物的发光敏化。复合物的发光衰减表现出双指数行为。寿命短的组分归因于
配体的荧光,而寿命长的组分与Ho 3+发射有关。使用荧光寿命成像,表明在所研究的复合物中存在单一类型的发射位点。根据光学测量的结果,研究Ho 3+的能图复合体被开发出来。结果表明,从
配体环境的激发三重态能级到Ho 3+的5 F 5能级的能量转移是络合物中离子发射的原因。
