Published: May 14, 2024

The construction of a highly luminescent, stable, and target-insensitive internal reference signal is significant in ratiometric color tonality applications. Improvement the antenna effect, efficient mechanism that enhances luminescence emission via sensitization, an effective route to obtain bright luminescence. Additionally, manipulation crystal structure morphology key issue control reactivity, especially metal–organic frameworks (MOFs). In present work, novel red emitter Eu/Zn bimetal biligand MOF (UoZ-5) was synthesized used as signal. A dual-antenna from triplet states (T1) ligands 5Do Eu3+ ion, observed explained on basis energy levels. With UoZ-5 serving reference, blue-emitting carbon quantum dots (CQDs) selective for Ag+ ions nonfluorescent composite, CQDs@Ag+, probe vitamin B1, tonality-based platform analysis were developed.
