Controllable synthesis and assembly of functional nanomaterials with quasi-atomic precision for the construction of cross-scale high-performance devices remains a challenge for existing technologies in synthetic chemistry and micro- and nanofabrication. Our group is dedicated to the issue of multi-scale precision synthesis of rare-earth inorganic nanomaterials, creating large-area and high-precision assembly synthesis methodologies at the nanoscale, and investigating the performance improvements brought about by novel materials and architectures for optical and electrical devices. On the one hand, rare-earth-doped nanocrystals with sub-nanometer precision are designed and manufactured with an emphasis on the epitaxial growth reaction mechanism and ion doping in solution systems to ensure the material foundation for cross-scale assembly. On the other hand, centimeter-scale arrays of three-dimensional composite rare-earth nanomaterials on solid-state matrices were built using a combination of nucleic acid-mediated assembly and micro- and nanofabrication methods. By integrating theory and experiment, we investigate the relationship between the structure and function of three-dimensionally produced nanomaterials with the goal of developing advanced nano-optical and electrical devices.

Specifically, including but not limited to the following areas:

(1) Synthesis and Cross-Application of rare Earth Nanomaterials;

(2) Rare earth-based nano-photons and nano-electronic materials and devices;

(3) Cross-scale Integrated Machining of low-dimensional Nanomaterials.
