Key Points

The study investigates the fluorescence properties of nanoparticles made from two quadrupolar dyes.
Synthesis of binary dye-based fluorescent organic nanoparticles with varying proportions of A and D dyes.
Analysis of excitation energy transfer efficiency in the nanoparticles.
Characterization of fluorescence behavior under different excitation conditions.
Ultrafast excitation energy transfer was observed in the nanoparticles.
The efficiency of fluorescence was remarkably high due to the cooperative interactions between the dyes.
Unusual fluorescence behavior was noted, indicating potential for novel applications.

Implication

Binary dye-based nanoparticles demonstrate efficient energy transfer, suggesting new fluorescence applications.

Abstract

Binary dye-based fluorescent organic nanoparticles, composed of varying proportions of A and D - two structurally related quadrupolar dyes - exhibit ultrafast and remarkably efficient excitation energy transfer, which in...
