What it means

Reach for it when describing a scientific light-emission phenomenon or its soft visual effect
The plankton's blue luminescence traced each paddle stroke.
Choose between these
6- everyday
plain description of steady soft light is enough
not when Glow can result from heat and does not identify the physical process.
- warm
shimmer
changing reflected highlights create the effect
not when Shimmer is usually reflection, not emitted luminescence.
- professional
fluorescence
emission stops almost immediately when excitation ends
not when Fluorescence names a different timing behavior than phosphorescence.
- professional
phosphorescence
light continues after the exciting energy source is removed
not when Phosphorescence is one type of luminescence, not an interchangeable general term.
- formal
bioluminescence
a living organism produces the light
not when Bioluminescence is too narrow for minerals, chemicals, or devices.
- literary
the visual impression of emitted light matters more than mechanism
not when Radiance says nothing about temperature or production.

It naturally appears in
3- blue luminescence
Blue luminescence appeared when the mineral met ultraviolet light.
