Organic nanoparticles (O-dots) with a high photoluminescence quantum yield (94%) and long-lived delayed emission (3.1 μs) originating from thermally activated delayed fluorescence (TADF) were developed as glassy state particles using an oil in water emulsion under high pressure (<20 bar). The TADF glassy O-dots exhibit not only good dispersibility and high photostability in water but also good uptake properties into living cells. The glassy O-dots will open new uses as organic emitters in biological applications.
具有高光致发光量子产率（94%）和源自热激活延迟荧光（TADF）的长寿命延迟发射（3.1微秒）的有机纳米颗粒（O点），在高压（<20巴）下通过水包油乳液被制备为玻璃态颗粒。TADF玻璃态O点不仅在水中具有良好的分散性和高光稳定性，而且对活细胞具有良好的摄取特性。玻璃态O点将为生物应用中的有机发光体开辟新的用途。
