Divalent europium (Eu) in small amounts is the activator of the bright blue fluorescence of some samples of the mineral fluorite (CaF).

The Princie also has the property that when exposed to ultraviolet light it displays bright orangey-red fluorescence.

Fluorescent (millipedes in the tribe Xystocheirini display some of the brightest fluorescence of the U.S. Xystodesmidae species)

Green is a dark color - not a dreadful bright fluorescence.

The difference between the absence and presence of X rays was a difference between total darkness and a bright fluorescence.

These have been found to have brighter fluorescence and reasonable efficiencies.

These ubiquitous dyes are the reason for the bright blue fluorescence of many papers and fabrics under UV.

Zinc protoporphyrin, formed in developing red blood cells instead of hemoglobin when iron is unavailable or lead is present, has a bright fluorescence and can be used to detect these problems.

After the photoconversion, the photoconverted Kaede protein emits bright and stable red fluorescence.

Besides, before the photoconversion, Kaede emits bright green fluorescence which enables the visualization of the localization of the non-photoacivated protein.
