The physics analysis platform aims at improving the ability of computing and data storage according to accumulated data volume, detector calibration, event reconstruction, MC tuning,and analysis efficiency. The computing resources and hard disks have been increased. A computing resource monitoring system and a computing environment management system were developed. A 574TB Lustre data storage system was established. According t
o the Daya Bay network and computing environment, an onsite network support platform was designed and implemented. The data buffer module as well as the monitor system was deployed at both onsite and IHEP for better data transfer. For the offline software, a calibration algorithm was developed using cosmic muon events to get the time latency between different detectors.The layer noise rate and module noise rate of the resistive plate chambers were obtained with the forced trigger events. A MC Tuning software framework was developed to manage simulation parameters. A new lightweight analysis framework was proposed and the data model was defined as well as the event buffer mechanism.

摘 要:(1)应用量子理论,在Marcus理论基础之上,研究了蓝磷光体系三芳基Pt配合物的发光性质,并提出了量子效率优化方案。扭曲结构D-A分子具有局域和电荷转移杂化态HLCT性质,在理论上形成单三线态激子时也有可能突破量子自旋统计,即单线态激子的形成比例会超过25%,同时材料本身也有较高的光致发光效率,因而在电致发光器件方面可能会有很好的性能。(2)设计合成了一系列含有配位碳原子的四齿配体,并进一步合成了基于这些刚性配体的铂(II)配合物,通过稳态光谱和超快光谱对铂(II)配合物的光物理性质进行了深入研究,利用密度泛函理论对配合物的基态和激发态性质进行了理论分析,总结了电荷跃迁位置和类型变化的控制因素,探索了这些强磷光材料在光电器件中的应用。(3)在强磷光发射和长激发态寿命的金(III)和钯(II)配合物及其在光催化太阳能转换、能量上转换、双光子吸收和磷光OLED中的应用等方面取得了阶段性进展。
(4)在廉价金属(锌、铜和钨)配合物荧光/磷光材料的设计合成及光电应用、不含金属的有机小分子磷光发射方面取得突破性进展,观察到了有机分子的电致磷光。(5)以三核吡唑基d10金属(CuI,AgI,AuI)配位单元为主要研究对象,通过合成和配体设计对三核单元间的聚集态结构进行调节,实现了对其聚集体的光物理过程的调控。(6)利用晶态光功能配位超分子聚集体的协同作用、异相反应和动态孔性,进行了研磨致发光变、异相催化和染料降解、选择性发光传感等应用研究。对

Abstract : (1)Combining Marcus theory with tight binding DFT, a new high efficient luminescent material was designed based on the detailed exploration of excited state and radiation constant of a serials of Pt complex. A twisting donor–acceptor TPA-NZP exhibits fluorescent emission through a hybridized local and HLCT. (2)Designed and synthesized a series of rigid Pt(II)complexes with tetradentate ligands. Through a combination of ultra-fast spectroscopic characterizations and theoretical calculations, we investigated detailedly the photophysical properties of these metal complexes, summarized the basic rules for tuning of the excited-state properties of metal complexes, and explored their applications in optoelectronic materials. (3)Made progress in the application of strongly luminescent Au(III) and Pd(II) complexes with long-lived excited states on photophysics,photochemistry, and OLEDs. (4)designed and synthesized inexpensive metal complexes (Zn, Cu, W complexes) and organic molecules for photocatalysis and OLEDs. (5)Taking trinuclear d10 metal pyrazolates as structural units, the regulation of photophysical process of these aggregates were realized by adjusting the structure of these trinuclear aggregates. (6) Utilizing the inherent properties of
synergistic interactions, heterogeneous reactions, dynamic porosity in crystalline aggregates, the application of mechanochromism, heterogeneous catalysis, dye degradation and selective luminescence sensor were achieved. (7)Introducing dynamic covalent bond into the synthesis of coordination supramolecular aggregates, two kinds of imidazolate coordination supramolecular aggregates were prepared through subcomponent self-assembly. (8) Designed and prepared 16 metal complexes as photosensitizers and catalysts, systematically investigated their UV absorption, electron excitation and transfer processes. Investigated the photocatalytic hydrogen production activities of theses complexes in the presence of a sacrificial electron donor in a three component photocatalytic system. (9) Designed and synthesized low-triplet-energy host materials for blue phosphor, and provided a new idea for the design of host materials. Proposed the concept of "hot exciton " and HLCT matrials, which present a kind of new low-cost and high-efficiency fluorescence materials. Developed a type of interface technology by sol-gel methods that significantly improved the lifetime of the device.
