기능성 재료 및 에너지 연구실(functional Materials and energy Lab (funMat Lab))

Electroluminescence (EL) is a process by which photons are generated when the excess electron-hole pairs are created by an electric current caused by an externally applied bias. It is known as the desired driving system in LEDs in terms of less energy loss that occurs from the operation of EL-LEDs than LCD due to the backlight. Halide perovskites have emerged as a promising optoelectronic material for light-emitting diodes. We are working on the synthesis of lead and lead-free perovskite Nanocrystals (NCs) for emissive layers. Our group research on charge transport layers (CTLs) including hole transport layers (HTLs) and electron transport layers (ETLs) in LED structure to improve the operational stability and efficiency.
