报告摘要

　　Quantum dot nanocrystal materials, acknowledged with the prestigious 2023 Chemistry Nobel Prize, are emerging as pivotal tools that are transforming both fundamental science and technological applications. Their unique properties make them highly versatile, particularly in serving as exceptional emissive materials with great potential across a wide range of applications. In this presentation, I will discuss about our experimental efforts focused on the synthesis and characterizations of different isotropic and anisotropic quantum dot nanomaterials. These dots exhibit superior optical and optoelectronic performance metrics relying on their unique exciton generation, consolidating desirable properties within a single material. Subsequently, I will illustrate how these colloidal nanocrystals can serve as fundamental building blocks, enabling the creation of higher-order architectures in assemblies with crystalline as well as quasicrystalline superstructures. Throughout the talk, I will delve into several quantum dot nanocrystal-based applications investigated in our laboratory. This exploration highlights the multifaceted capabilities of quantum dot nanocrystals and their potential impact on advancing innovative technologies and scientific understanding.

嘉宾简介

Professor Ou Chen earned his B.S. degree in Chemical Physics from the University of Science and Technology of China (USTC) and completed his Ph.D. studies in the Department of Chemistry at the University of Florida in 2010. Following this, he conducted postdoctoral research with Prof. Moungi Bawendi (2023 Nobel Laureate in Chemistry) at MIT before joining Brown University as a faculty member. His research endeavors focus on unraveling the fundamental mechanisms underlying the synthesis, characterizations, and assembly of semiconductor quantum dots, perovskite nanocrystals, and heterostructural nanomaterials. These materials are explored for diverse applications, including photocatalysis, light emitting diode, and solar energy harvesting. Prof. Chen has published over one hundred publications in high impact journals including Nature, Science, Nature Materials, Nature Nanotechnology, Nature Chemistry, Nature Communications, JACS, Angrewandte Chemie, Advanced Materials, etc.. Professor Chen's contributions to the field have been recognized through various prestigious awards, including the NSF Career Award, Sloan Research Fellowship Award, Camille Dreyfus Teacher-Scholar Award, and 3M Faculty Award, among others.
