Narrowband Organic Afterglow Materials Exhibiting 11.2 nm FWHM, 38% Phosphorescence Efficiency and 1.5 s Emission Lifetime Under Ambient Conditions
{{output}}
Narrowband organic room-temperature phosphorescence (RTP) remains rare due to significant high-frequency vibronic coupling in T1→S0 electronic transition, where T1 and S0 represent the lowest triplet excited state and ground state, respectively. Here, we repo... ...
