A fluorophore (or fluorochrome, similarly to a chromophore) is a fluorescent chemical compound that can re-emit light upon light excitation. Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several π bonds .

A fluorophore is a fluorescent chemical compound that can absorb photons in the “ground state,” leading to fluorescence emission and vibration relaxation in the “excited state.” From: Engineering, 2022

A fluorophore is a chemical compound that is fluorescent, meaning it emits strong glowing colours. Quantum dots, conjugate organic molecules and some proteins are common fluorophores.

Fluorescence in situ hybridization (FISH) requires nucleic acid probes, including deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or nucleic acid analogs, labeled directly with fluorophores...

The basic fluorescence properties of a fluorophore—excitation and emission—are often presented in the form of line graphs. These curves describe the likelihood that excitation and emission will occur as a function of wavelength and provide important information about the expected behavior of the irradiated fluorophore.
