The next-generation LED device design and fabrication : Pb & Pb-free perovskite EML (emissive layer), novel CTL (charge transport layer)

What is electroluminescent LED device?

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.

Pb & Pb-free perovskite emissive layer (EML)

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 quantum dots (QDs) for emissive layers.

Charge transport layer (CTL)

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.

XR(eXtended Reality) display applications : Color converting layers for micro LEDs

We are researching color-converting materials for the next-generation display such as XR(eXtended Reality) display, which is an umbrella term encapsulating Augmented Reality(AR), Virtual Reality(VR), Mixed Reality(MR), and everything in between.

Luminescent materials for various applications : White LEDs, Security materials

Phosphor-converted white light-emitting diodes (pc-WLEDs) are efficient light sources used in lighting, high-tech displays, and electronic devices. Our group defined zero thermal quenching which compensates the emission losses with increasing temperature.
