phosphorescent

Phosphorescence is a type of photoluminescence related to fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with "forbidden" energy state transitions in quantum mechanics. As these transitions occur very slowly in certain materials, absorbed radiation is re-emitted at a lower intensity for up to several hours after the original excitation.

Everyday examples of phosphorescent materials are the glow-in-the-dark toys, stickers, paint, and clock dials that glow after being charged with a bright light such as in any normal reading or room light. Typically, the glow slowly fades out, sometimes within a few minutes or up to a few hours in a dark room. Wikipedia, phosphorescent

Keely
"The light that emanates from a glow worm is the resultant of the action of the sympathetic medium of the insect on a center of phosphorescent matter, which is included in its structure. The resultant of the two conditions are quite different, but they are governed by the same laws of sympathetic percussion." Snell Manuscript

"Dr. Macvicar, in his theories of the bearing of the cosmical law of assimilation on molecular action, says: "During this retreat of matter into ether in single material elements or units of weight, the molecules and masses from which such vaporization into the common vapor of matter is going on, may be expected to be phosphorescent." This surmise Keely has, over and over, demonstrated as a fact, also showing how gravitation operates as a lever, etheric wave motion, concentration under vibratory concussion, and negative vacuous tenuity."
