Synthetic chemistry and optoelectronic applications of nanocrystals
Nanocrystals, Optoelectronic materials, Synthetic chemistry, LEDs, solar cells
概要
Colloidal nanocrystals have emerged as a class of nanoscale optical materials for optoelectronic applications. However, most colloidal nanocrystals suffer from tedious synthesis methods and existence of toxic elements. My work focuses on the development of novel colloidal nanocrystals that hold potential for LED and photovoltaic applications. Specifically, I try to accelerate the screening of optimal synthetic conditions based on the combination of theoretical calculations and high-throughput experiments. I then use the synthesized nanocrystals with excellent optical properties for constructing high-performance LEDs and solar cells.

内容
Based on density function theory calculations and molecular dynamics simulations, the chemical potential-dependent formation energies of various defects and the most detrimental point defect for the ra-diative recombination of charge carriers in targeted systems can be known. Using these critical information as a guidline, colloidal synthesis strategies that benifit the suppression of defect formation are designed. By this means, I have sucessfully synthesized highly luminescent tin halide perovskite nanocrystals, and will use the concept of "theory-guided synthetic chemistry" to synthesize more nanocrystals with excellent optical properties.
まとめ
The use of "theory-guided synthetic chemistry" makes it possible to synthesize hard-to-synthesize colloidal nanocrystals in a labor/resource/time-saving manner. The obtained nanocrystals with excellent optical properties could find broad applications in LEDs and other optoelectronic devices.
