A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy.
The term phosphor had been used since the Middle Ages to describe minerals that glowed in the dark. One of the most famous, but not the first, was Bolognian phosphor. Around 1604, Vincenzo Casciarolo discovered a "lapis solaris" near Bologna, Italy. Once heated in an oxygen-rich furnace, it thereafter absorbed sunlight and glowed in the dark.
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
Imberline is a woven fabric with various colored stripes in the warp, often separated by gold thread. The fabric is often used in upholstery and drapery manufacture. intarsia Intarsia is a knitting technique used to create patterns with multiple colours. interfacing A type of material used on the unseen or "wrong" side of fabrics in sewing.
Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.
Pile cloth fabric applied as filter medium for water and wastewater treatment. Today, woven pile cloth media are used as filter media, which is the reason for the name of the process. [4] [5] Woven pile clothes have a multidimensional structure consisting of a filter-active fluidizable pile layer and a non-filter-active backing. [5]
The phosphor typically used for a near 368 to 371 nanometer emission peak is either europium-doped strontium fluoroborate (SrB 2 F 8: Eu 2+) or europium-doped strontium borate (Sr 3 B 2 O 6: Eu 2+) while the phosphor used to produce a peak around 350 to 353 nanometres is lead-doped barium silicate (BaSi 2 O 5: Pb +). "Blacklight blue" lamps ...
Depending on the desired property, a nanofabric is either constructed from nanoscopic fibers called nanofibers, or is formed by applying a solution containing nanoparticles to a regular fabric. Nanofabrics research is an interdisciplinary effort involving bioengineering , [ 5 ] molecular chemistry , physics , electrical engineering , computer ...
