Abstract
A light-emitting diode (LED) for plant illumination includes a substrate, and a PN-junction light-emitting portion over the substrate. The light-emitting portion has a strained light-emitting layer with a component formula of GaXIn(1-X)AsYP(1-Y) (0<X<1 and 0<Y<1), and a barrier layer, forming a 2˜40-pair alternating-layer structure with the strained light-emitting layer.
