Abstract
Embodiments of the invention include an n-type region, a p-type region, and a light emitting layer disposed between the n-type region and the p-type region. The light emitting layer is a III-V material comprising nitrogen and phosphorus. The device also includes a graded region disposed between the light emitting layer and one of the p-type region and the n-type region. The composition of materials in the graded region is graded.
