In article number 1800008, Dong‐Hwan Kim and co‐workers demonstrate highly efficient green single‐band upconversion luminescence under a near‐infrared light source through the largely elevated transition probability of a specific transition pathway in a liquid‐quenched amorphous host material. An ultrafast decay time results, which is 2–3 orders of magnitude faster than previously reported values.

上转换发光：液体淬灭的无定形基质中的超快单波段上转换发光（Adv。Mater。25/2018）

在编号1800008中，金东焕和他的同事通过在液态淬灭的非晶态基质材料中特定跃迁路径的跃迁概率大大提高，证明了在近红外光源下高效的绿色单波段上转换发光。结果是超快的衰减时间，比以前报告的值快2–3个数量级。
