半导体发光二极管 在正向偏置下,半导体PN结或与其类似的结构能够发出可见光或近红外光,这种把电能直接转换为光能的器件称为发光二极管,简称LED。 发光是物体内部以某种方式储存的能量转化为光辐射的过程。发光物体的光辐射是材料中受激发的电子跃迁到基态时产生的。半导体(主要是元素周期表中Ⅲ族和Ⅴ族元素构成的化合物半导体)发光二极管属于电流激发的电致发光器件。 电致发光现象发现于1923年,当时并没有引起人们的注意。随着近代技术的发展,对发光器件提出了新的要求,希望发光管简单、可靠、寿命长、价格低、小型化。所以自60年代开始电致发光的研究非常活跃。 发光机理 原子、分子和某些半导体材料,能分别吸收和放出一定波长的光或电磁波。根据固体能带论,半导体中电子的能量状态分为价带和导带,当电子从一个带中能态E1跃迁(转移)到另一带中的能态E2时,就会发出或吸收一定频率(υ)的光。υ与能量差(墹E=E2-E1)成正比,即
