Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal. This distinguishes luminescence from incandescence, which is light emitted by a substance as a result of heating. Historically, radioactivity was thought of as a form of "radio-luminescence", although it is today considered to be separate since it involves more than electromagnetic radiation. The term 'luminescence' was introduced in 1888 by Eilhard Wiedemann.
The dials, hands, scales and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as 'luminising'.
The following are types of luminescence:
Luminescence by David Biedenbender performed by the University of Texas at Austin Wind Symphony and Robert Carnochan on April 6, 2015. for more information, visit: http://www.davidbiedenbender.com/luminescence/ "Luminescence" is based on fragments from the melody "Break Forth O Beauteous Heavenly Light," which was written by Johann Schop (ca. 1590–1664) and subsequently harmonized in several settings by Johann Sebastian Bach. "Break Forth O Beauteous Heavenly Light" was first known as “Ermuntre dich, mein schwacher Geist” (Rouse thyself, my weak spirit), and was published in Lepzig in 1641 in Johann Rist’s Himmlische Lieder (Heavenly or Celestial Songs), where the tune appeared in triple meter along with text by Rist. Johann Sebastian Bach probably found an altered version of the tune ...

Types of Luminescence Luminescence is a non-thermal glow of substance that occurs after the substance absorbs excitation energy. For the first time luminescence was described in the XVIII century. Initially, the phenomenon of luminescence was used in the manufacture of luminous paints and luminous mixtures based on phosphorus to apply them to the scales of devices intended to be used in the dark. In the USSR luminescence hadn't attracted any special attention until 1948, when a soviet scientist, S.I. Vavilov, at a session of the Supreme Council proposed to produce economical luminous lamps and to use luminescence for the analysis of chemical substances. In our everyday life luminescence phenomenon is often used in luminous "daylight" lamps and CRTs. The phenomenon of luminescence lies at t...
Running some other way,
Got to get out
You’re already too late
To think of some other way now,
Dedicating endless plaques to friends
You’re not proud
Proud of something that’s changed
Changed your inner mind
You’re already too late;
The cycle starts with a shout loud,
What follows next was never planned,
Well, not that you knew
All words drown out
You’re falling down
--------
Reeling and feeling its dragging you down
You can’t deny
Our slow decline
But ever since I
I’ve changed you cry
This timeless lie
Is growing on me
It’s all that’s left of me
My life my fight my time my vice my crime
You'll never relate to what it feels like
Cos its already too late
To feel a thing when your
Insides, are full of hate
And there's no way to fake decisions
It’s a subliminal fate
It wraps itself round
Your fear of what is blowing away
The world it seems
Is weighing down on you like a mirror
Is it just a splinter
Of all we lost
-----------
Caught in the spotlight but no-one is ever looking at you
You can’t deny
Our slow decline
Accelerates mine
I’ve changed you cry
This timeless lie
Is growing on me
It’s all that’s left of me
My life my fight my time my vice my crime
------------------------------------------+
All that you break is our shared fall
But you cant recall
The scale of it all
