Title: Seunghee Choi: Innovator in Light-Emitting Devices

Introduction

Seunghee Choi is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of light-emitting devices, particularly through his innovative patent that focuses on the use of fluorescent compounds.

Latest Patents

Seunghee Choi holds a patent for a light-emitting device that includes a fluorescent compound. The device features an organic layer situated between a first electrode and a second electrode. Upon excitation, excitons in an-π* excited state of the fluorescent compound migrate to a π-π* excited state through reverse intersystem crossing with a Rate (rISC). This process leads to a radiative transition to a ground state, resulting in light emission via fluorescence. The fluorescent compound is characterized by a ratio of Rate (rISC) to Rate (IC) of 0.5 or greater. Additionally, the patent includes an electronic apparatus that incorporates the light-emitting device and the fluorescent compound.
