Using the high quality of Al(acac)3-NC films as emitting layers, the fabricated green perovskite LEDs showed high color purity with a very narrow full width at half maximum (fwhm, 16.8 nm) and effective charge injection with low turn-on voltage (<2.0 V). He also debuted as a solo artist in 2018 with a single called 'Yesterday Azora.' Before Fame He moved to China as a trainee under Banana Entertainment.

Al(acac)3-NC film can maintain 94% of the initial PLQY after being stored 3 days under ambient environment. There are some reasons that are difficult to put into words. Therefore, the CsPbBr3 NC films with high photoluminescence quantum yield of 88% and the stability of ligand-treated NC film has been significantly promoted as well. To overcome the limitations, the post-treatment strategy is adopted by using aluminium triacetylacetone (Al(acac)3) ligand to exchange the insulating ligand and simultaneously passivate the lead defects of CsPbBr3 NCs with large size.
However, the weakly bound ligands such as oleic acid and oleylamine of perovskite NCs result in surface defects and hinder the charge carrier transport in the emitting layers. Cesium lead-halide perovskite nanocrystals (NCs) have emerged as a great potential for next-generation light-emitting diodes (LED) applications due to their high color purity, tunable optical bandgaps, and controllable synthesis.
