无中微子双beta衰变实验，因其可判定中微子的Majorana属性，并且可以间接测量中微子的质量，成为中微子前沿领域最重要的实验之一。结合中国的实际，江门中微子实验JUNO在完成质量顺序测量后，可在其探测器中心放置一个加载0vββ衰变核素的液闪球，进行0vββ衰变测量。怎样将0vββ衰变核素加载到JUNO实验的液体闪烁体内，怎样降低其放射性本底？是亟待研究的问题。另外，能量分辨率由JUNO实验的3%@1MeV提高到0vββ实验要求的1%@2.4MeV，怎样提高液闪的光产额也是关键问题。本项目针对以上问题，建议以量子点为载体加载0vββ衰变核素，研究加载量子点后的液闪性能，进而研究以量子点为发光物质的新型液体闪烁体。本项目瞄准中微子实验前沿与闪烁体研究前沿，具有原创性，对我国0vββ衰变实验具有重要意义。

Neutrino-less double beta decay experiment is one of the most important experiments in the field of neutrino because it can determine the Majorana property and can measure the effective mass of neutrinos. By considering the reality of China, Jiangmen neutrino experiment JUNO can do 0vββ decay experiment after the completion of mass hierarchy measurement, by placed a liquid scintillator ball loaded by 0vββ decay nuclide in the center of the JUNO detector. The key issues are how to load 0vββ decay nuclide into the liquid scintillator of the JUNO experiment, and how about the radioactive background and detection performance. In addition, how to improve the energy resolution from the JUNO’s 3% @ 1MeV to 0vββ experimental requirements of 1% @ 2.4MeV is also a key issue. In view of the above problems, quantum dots are proposed as the carrier for loading the 0vββ decay nuclide, and the performance after loading will be studied. Furthermore, a new type of liquid scintillator with quantum dots as luminescent material will be researches. This project is an original innovation combining with the frontier of the neutrino and scintillator, and has great significance to the future 0vββ decay experiment in China.
