Förster Resonance Energy Transfer: An Efficient Way to Develop Stimulus-Responsive Room-Temperature Phosphorescence Materials and Their Applications

In this work, Förster resonance energy transfer (FRET) is utilized to construct a stimulus-responsive room-temperature phosphorescence (RTP) system. Owing to the specificity of the FRET system and its sensitivity to distance, the resultant material shows turn-on persistent RTP emission upon force or heating stimulus. Furthermore, a near-perfect compatibility with existing printing technology is demonstrated for this material, especially for thermal printing. This finding could provide a simple, efficient, and truly commercially viable construction strategy for RTP material.
