Electroluminescent devices are fabricated using either organic or inorganic electroluminescent materials. The active materials are generally semiconductors of wide enough bandwidth to allow exit of the light.
The most typical inorganic thin-film EL (TFEL) is ZnS: Mn with yellow-orange emission. Examples of the range of EL material include:
Powdered zinc sulfide doped with copper (producing greenish light) or silver (producing bright blue light)
Thin-film zinc sulfide doped with manganese (producing orange-red color)
Naturally blue diamond, which includes a trace of boron that acts as a dopant.
Semiconductors containing Group III and Group V elements, such as indium phosphide (InP), gallium arsenide (GaAs), and gallium nitride (GaN).
Certain organic semiconductors, such as [Ru(bpy)3]2+(PF6-)2, where bpy is 2,2'-bipyridine.
Do you know now there is el flashing t shirt? With the continuous development and application of new materials, as well as interdisciplinary rise in various fields, theatrical costumes can proceed from the functional and intelligent angle; they become a major role at the stage set to reflect the stage of conscious and proactive environment. The light-emittingmaterial is by virtue of advances in technology to a greater extent determines the dominant direction of the stage design and reducing relative dependence on the stage layout and lighting design.
In recent years, enterprises develop visible light-induced luminescence (also known as storage luminous materials), ultraviolet, photoluminescence, luminescent rare earth luminescent materials and so on. Among them, electroluminescent materials can produce by power generation light energy light-emitting. The electroluminescent also be divided into a high electric field light-emitting material (also known as the intrinsic luminescence) and low electroluminescent (also known as injection type light emitting). The former light-emitting material is an inorganic powder, the film material and the organic material, the latter is the transistor material of the light emitting diode.
