The authors demonstrate QLEDs implementing wider active layers (50 nm) based on QD-conducting polymer nanohybrids, which exhibit a stable operational device performance across a wide range of current densities and brightness. A comparative study reveals that the significant suppression of efficiency roll-off in the high c.d. regime is primarily attributed to a sufficient charge carrier distribution over the wider active layer and improved charge carrier balance within QDs enabled by the hybridization of QDs with conducting polymers. Use of this finding in future studies should greatly facilitate the development of high performance, stable QLEDs at high c.d. or luminance regime toward displays or solid-state lighting applications. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Product Details of 27249-90-7).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Product Details of 27249-90-7
