It made a loud whack and suffused her butt with a red fluorescence.

The original red fluorescence was besieged by a vigorous purple shimmer sweeping down the shell from the northern endcap.

A pale red fluorescence slowly grew more brilliant as the black light played over the surface.

Then the red fluorescence glowed, bright and malicious, as the black light transmuted the invisible into something resembling blood.

An aliquot of Kaede protein was discovered to emit red fluorescence after being left on the bench and exposed to sunlight.

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

In addition, as both green and red fluorescence of Kaede are excited by blue light at 480 nm for observation, this light will not induce photoconversion.

Acridine orange emits from yellow, orange, to red fluorescence when the pH get lower in the acidic vacuole of the living cell.

Trivalent chromium at low concentration is the source of the red fluorescence of ruby.

It shows red fluorescence with maxima at 649 and 717 nm.
