For the commercial next generation QD display, there is an urgent need to prepare environmentally friendly QDs that show high efficiency and better color purity. From this perspective, a strategy for tuning the wavelength and spectral width to optimize the brightness and color space agreement will be discussed. The critical parameters affecting photophysical properties, such as InP core uniformity, the thickness and shape of the ZnSe shell, the electron/hole distribution, surface dangling defects, oxidative phase, and the stacking faults, should be carefully examined. The qualitative and quantitative analytical methods are important to understand the nature of the ligands on the QDs for various applications. For further development of QD-LED displays, it is required to prepare more efficient and stable green and blue-emitting QD by passivating interface defect structures and to understand of the degradation mechanisms. |
