中文百科

电致发光 Electroluminescence

(重定向自Destriau effect)
一种蓝/绿电致发光的灯源的光谱,(与上图所示相同)波峰波长492 nm,而半峰全宽则很宽达85 nm.
一种电致发光的蓝光夜灯(0.08 W,230 V,1960开始照亮,灯宽59 mm)

电致发光亦称电场发光(Electroluminescence,EL),是指电流通过物质时或物质处于强电场下发光的现象,在消费品生产中有时被称为冷光。电致发光物料有:掺杂了铜和银的硫化锌、蓝色钻石(含硼)、砷化镓等。目前电致发光的研究方向主要为有机材料的应用,已有的应用为电致发光显示器(ELD)。

Electroluminescence 电致发光

(重定向自Destriau effect)
Spectrum of a blue/green electroluminescent light source for a clock radio (similar to the one seen in the above image). Peak wavelength is at 492 nm and the FWHM spectral bandwidth is quite wide at about 85 nm.
An electroluminescent nightlight in operation (uses 0.08 W at 230 V, and dates from 1960; lit diameter 59 mm)
The world's first electroluminescent billboard campaign, Canada, Winter 2005
1966 Dodge Charger instrument panel with electroluminescent lighting. Chrysler first introduced cars with EL panel lighting in its 1960 model year.

Electroluminescence (EL) is an optical phenomenon and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body light emission resulting from heat (incandescence), from a chemical reaction (chemiluminescence), sound (sonoluminescence), or other mechanical action (mechanoluminescence).
