镧系掺杂纳米晶的电致发光:通过电致激子实现高效LnLEDsOA
Electroluminescence from Lanthanide-doped Nanocrystals:Achieving High-efficiency LnLEDs via Molecular Excitons
镧系掺杂纳米晶因其强绝缘性长期无法实现电致发光.最新研究通过在纳米晶表面引入可电激发的有机分子配体,利用分子激子作为能量中介,实现了高效、可调谐的可见及近红外镧系电致发光二极管.该策略突破了镧系纳米晶电激活发光的瓶颈,为高色纯度显示和近红外光源提供了新路径.
Lanthanide-doped nanoparticles(Ln NPs)have long been regarded as electrically inactive due to their insulating hosts.A recent strategy enables electrical activation by introducing exciton-forming organic ligands as energy mediators,achieving efficient and color-tunable visible and near-infrared Ln LEDs.This breakthrough overcomes the insulation bottleneck and opens new opportunities for high-color-purity displays and infrared photonic devices.
