A phosphor, most generally, is a substance that exhibits the phenomenon of luminescence. Somewhat confusingly, this includes both phosphorescent materials, which show a slow decay in brightness (> 1 ms), and fluorescent materials, where the emission decay takes place over tens of nanoseconds. Phosphorescent materials are known for their use in radar screens and glow-in-the-dark toys, whereas fluorescent materials are common in cathode ray tube (CRT) and plasma video display screens, sensors, and white LEDs.
Phosphors are often transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT displays and fluorescent lights. CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number.
Phosphorus, the chemical element named for its light-emitting behavior, emits light due to chemiluminescence, not phosphorescence;
A material can emit light either through incandescence, where all atoms radiate, or by luminescence, where only a small fraction of atoms, called emission centers or luminescence centers, emit light. In inorganic phosphors, these inhomogeneities in the crystal structure are created usually by addition of a trace amount of dopants, impurities called activators. (In rare cases dislocations or other crystal defects can play the role of the impurity.) The wavelength emitted by the emission center is dependent on the atom itself, and on the surrounding crystal structure.
Wikimedia Commons (or simply Commons) is an online repository of free-use images, sound, and other media files. It is a project of the Wikimedia Foundation.
Files from Wikimedia Commons can be used across all Wikimedia projects in all languages, including Wikipedia, Wikibooks, Wikivoyage, Wikispecies, Wikisource, and Wikinews, or downloaded for offsite use. The repository contains over 30 million media files. In July 2013, the number of edits on Commons reached 100,000,000.
The project was proposed by Erik Möller in March 2004 and launched on September 7, 2004. A key motivation behind the setup of a central repository was the desire to reduce duplication of effort across the Wikimedia projects and languages, as the same file had to be uploaded to many different wikis separately before Commons was created.
Several sister projects (e.g. Dutch, Swedish, Danish, Norwegian, Spanish, Basque, Polish, Czech and Slovak Wikipedias) moved all their media content to Commons and stopped allowing local uploading. Some projects, such as the English Wikipedia, have more compliant copyright policy and allow to upload and keep files which are not acceptable at Commons, e.g. fair use images.

Phosphor-Knappheit gehört zu den globalen Ökologie-Themen wie saurer Regen, Ozonschicht und Klimawandel. Es ist ein zentraler Baustoff allen Lebens, ohne den wir nicht existieren können. Deshalb muss es alarmieren, wenn internationale Experten warnen, dass die Reserven der Welt zu Ende gehen. Zahlreiche Wissenschaftler vergleichen die Verknappung von Phosphor mit der Endlichkeit der Ölreserven. Doch anders als beim Energielieferanten Öl gibt es für Phosphor keine Alternative. Phosphor ist ein echtes chemisches Element und lässt sich durch nichts ersetzen oder reproduzieren. Es ist ein ent...

Lo !
I pilgrim came from the desert
Draped in sickness, dressed in black
When the utter thunders roared young
And the heart of Valusia enshrined the dark
He was born of the whore
but was forged by wrath
And he was lusting for more
Born at Zins earthdawn
the halo of the chosen
foreshadowed the war
Promethean Phosphor
Beared the mark of hatelorn Saturn
And whispered requiems lurid to men
Natus sub Stella Polari
