Efficient and Stable Blue Quasi-2D Halide Perovskite Light-Emitting Diodes

Project description

High-efficiency blue light-emitting diodes based on halide perovskites

Metal-halide perovskites are a new generation of semiconductor materials that have been widely applied in numerous optoelectronic devices including perovskite light-emitting diodes (PeLEDs). The external quantum efficiencies (EQEs) of green and red emissive PeLEDs have exceeded 20 % which is comparable to organic LEDs at the lab scale. However, the performance of blue PeLED lags behind that of its counterparts (i.e. green and red PeLEDs) due to poor colour stability of blue emission which leads poor device performance and stability. The EU-funded Blue-PeLEDs project will work on improving the efficiency and colour stability of blue PeLED by designing quasi-2D perovskite materials. Further, these will be used to fabricate state-of-the-art efficient blue PeLEDs.
