Luminescent material

Emitting energy is an object of the absorption without hot stage, characterized by direct conversion of radiation phenomena. Light phenomenon widely exists in a variety of materials, there are different forms of light emitting semiconductor, insulators, organic matter and organisms.
Luminescent material is divided into two major categories of organic and inorganic. Usually capable of emitting light in the visible and ultraviolet region of the spectrum called crystalline inorganic crystal phosphors, and powdered luminescent material called phosphor
Commonly used by the excitation light emitting material is divided into:
(1)Photoluminescent Aluminum Sheet, the ultraviolet, visible and infrared light and excitation light, according to the luminescent properties, different scope of application, is divided into long-lasting light-emitting materials, light emitting materials and multi-photon emissive material.
(2) a cathode-ray-emitting material, an electron beam excitation light-emitting material, also known as electron beam excites the luminescent material.
(3) an electroluminescent material, by an electric field excitation light-emitting material, also known as the electroluminescent material.
(4) X-ray emitting material by X-ray radiation emitting material.
(5) chemiluminescent material, a chemical reaction of two or more chemical substances caused between the luminescent material.
(6) Radioactive luminescent material, natural or man-made radioactive materials and radiation-emitting material.
