Abstract

This invention provides a high-efficiency light-emitting device, which comprises a substrate, and an epitaxial crystal formed on the substrate. The substrate has a base surface and a plurality of cavities sunk from the base surface of the substrate apart from each other. The epitaxial crystal has a base surface and a plurality of posts projected form the base surface of the epitaxial crystal. The posts of the epitaxial crystal displaced in the cavities of the substrate respectively. Each of the cavities of the substrate and each of the posts of the epitaxial crystal cooperate to confine a plurality of closed pores.
