新型高效深蓝光铈(III)配合物

该数据集来自深蓝光吡唑硼类铈(III)配合物的光致发光和电致发光研究，其中包括配合物Ce-1和配体KTpMe2的紫外吸收光谱以及配合物Ce-1在DCM溶液和粉末发射光谱。通过两种配体对中心铈离子的5+3饱和配位，有效阻断了环境中的振动猝灭，获得了一种高效深蓝光发射和纳秒级激发态寿命的铈配合物，并证明了此类配合物在电致发光中具有100%的激子利用效率。所述数据在紫外吸收光谱仪（Shimadzu UV-3100 spectrometer）和荧光光谱仪（Edinburgh FLS-980）上采集获得，采集时间分别为粉末荧光光谱：2018年9月28日；溶液荧光光谱：2018年11月23日；紫外吸收光谱：2019年2月19日；粉末低温荧光光谱：2019年6月17日。采集地点为北京大学。该数据集对应于研究内容中新型稀土发光材料的研发。数据体量约为50 kB。

This dataset is derived from the photoluminescence and electroluminescence studies of deep-blue-emitting pyrazabole-based cerium(III) complexes. It includes the ultraviolet-visible (UV-Vis) absorption spectra of complex Ce-1 and ligand KTpMe2, as well as the emission spectra of complex Ce-1 in DCM solution and in the solid powder state. Through the 5+3 saturated coordination of the central cerium(III) ion by two ligands, vibrational quenching from the surrounding environment is effectively suppressed, yielding a cerium complex with efficient deep-blue emission and nanosecond-scale excited-state lifetime, and it is demonstrated that such complexes achieve 100% exciton utilization efficiency in electroluminescence applications. The data were collected using a Shimadzu UV-3100 spectrometer and an Edinburgh FLS-980 fluorescence spectrometer. The collection times are as follows: powder fluorescence spectrum: September 28, 2018; solution fluorescence spectrum: November 23, 2018; UV-Vis absorption spectrum: February 19, 2019; low-temperature powder fluorescence spectrum: June 17, 2019. The data collection was conducted at Peking University. This dataset corresponds to the research and development of novel rare-earth luminescent materials in the corresponding study, with a total data volume of approximately 50 kB.
