Is there a specific application or emission wavelength you are looking for?

Laser dye companies (like http://www.exciton.com/) will have selections of different types and wavelengths of emissive dyes available.

Tuhin Khan

Antracene, pyrene, coumarin, fluorescein and their derivatives are few of many commercially available uncharged fluorescent molecule. https://omlc.org/spectra/PhotochemCAD/

Klaus Koren

there are many

depends on what you want to use if for and spectral properties
