Facile preparation of solid-state fluorescent carbon dots with high fluorescence quantum yield and application in rapid latent fingerprints detection

Due to the direct π - π interaction and excessive energy resonance transfer, it is very challenging to prepare CDs with high fluorescence quantum yield (QY) in solid state. In...

Effective π-electron number and Symmetry Perturbation Effect on the Two-photon Absorption of Oligofluorenes

Fluorene-based molecules present significant nonlinear optical responses, multiphoton absorption in the visible, which, combined with the high fluorescence quantum yield in organic solvents, could make this class of materials potentially...

Unusually large fluorescence quantum yield for a near-infrared emitting DNA-stabilized silver nanocluster

Silver nanoclusters stabilized by 5′-CCCGGAGAAG-3′ DNA strands display an unusually high fluorescence quantum yield in the near-infrared region.

Achieving remarkable and reversible mechanochromism from a bright ionic AIEgen with high specificity for mitochondrial imaging and secondary aggregation emission enhancement for long-term tracking of tumors

An ionic AIEgen with high fluorescence quantum yield shows remarkable and reversible mechanochromism as well as excellent mitochondrial imaging of cancer cells and long-term tracking of tumors.

Forcing dimethylacridine crooking to improve the efficiency of orange-red thermally activated delayed fluorescent emitters

By crooking conventional donor segments via suitable steric hindrance, nearly planar geometries, a small singlet–triplet energy splitting and a high fluorescence quantum yield can be realized simultaneously.
