In 2018,Advanced Materials (Weinheim, Germany) included an article by Song, Jizhong; Fang, Tao; Li, Jianhai; Xu, Leimeng; Zhang, Fengjuan; Han, Boning; Shan, Qingsong; Zeng, Haibo. Recommanded Product: Indium(III) bromide. The article was titled 《Organic-Inorganic Hybrid Passivation Enables Perovskite QLEDs with an EQE of 16.48%》. The information in the text is summarized as follows:
Perovskite quantum dots (QDs) with high photoluminescence quantum yields (PLQYs) and narrow emission peak hold promise for next-generation flexible and high-definition displays. However, perovskite QD films often suffer from low PLQYs due to the dynamic characteristics between the QD’s surface and organic ligands and inefficient elec. transportation resulting from long hydrocarbon organic ligands as highly insulating barrier, which impair the ensuing device performance. Here, a general organic-inorganic hybrid ligand (OIHL) strategy is reported on to passivate perovskite QDs for highly efficient electroluminescent devices. Films based on QDs through OIHLs exhibit enhanced radiative recombination and effective elec. transportation properties compared to the primal QDs. After the OIHL passivation, QD-based light-emitting diodes (QLEDs) exhibit a maximum peak external quantum efficiency (EQE) of 16.48%, which is the most efficient electroluminescent device in the field of perovskite-based LEDs up to date. The proposed OIHL passivation strategy positions perovskite QDs as an extremely promising prospect in future applications of high-definition displays, high-quality lightings, as well as solar cells.

Indium(III) bromide(cas: 13465-09-3) is used in organic synthesis as a water tolerant Lewis acid. It efficiently catalyzes the three-component coupling of β-keto esters, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones.Recommanded Product: Indium(III) bromide
