Realizing efficient and ultralong room-temperature phosphorescence (RTP) is highly desirable but remains a challenge due to the inherent competition between excited state lifetime photoluminescence quantum yield (PLQY). Herein, we report bottom-up self-assembly of transparent metal-organic framework (MOF) bulk glasses exhibiting direct all-phosphorescence (lifetime: 630.15 ms) with PLQY up 75 % at ambient conditions. These macroscopic MOF have high Young's modulus hardness, which provide...
Harnessing the potential of thermally activated delayed fluorescence (TADF) and room temperature phosphorescence (RTP) is crucial for developing light-emitting diodes (LEDs), lasers, sensors, many others. However, effective strategies in this domain are still relatively scarce.
