In modern science, this distinction became important because some items, such as lasers, required the fastest decay times, which typically occur in the nanosecond (billionth of a second) range. In physics, this first mechanism was termed "fluorescence" or "singlet emission", and is common in many laser mediums such as ruby.

Scheelite is widely used in phosphors, [12] particularly in scintillators for X-ray and gamma-ray detection. [13] It is also utilized in fluorescent lighting systems for its ability to convert ultraviolet light into visible light. [14] In some cathode ray tubes (CRTs), calcium tungstate (Scheelite) is used as a phosphorescent screen material. [15]
[12] [13] [14] Similar X-ray emissions have also been observed with metals. [15] Opening an envelope sealed with polymer glue may generate light that can be viewed as blue flashes in darkness. [16] When sugar crystals are crushed, tiny electrical fields are created, separating positive and negative charges that create sparks while trying to ...
