Abstract
A light-emitting structure includes an n-type layer, an active layer, and a p-type layer. The active layer has N quantum well structure periods, each of the N quantum-well structure periods has a well layer and at least one barrier layer. The N quantum-well structure periods include a first light-emitting section and a second light-emitting section. The first light-emitting section is closer to the n-type layer than the second light-emitting section. A method for producing the light-emitting structure, and a light-emitting device that has the light-emitting structure are also disclosed.
