PHOSPHOR SINGLE CRYSTAL SUBSTRATE AND METHOD FOR PREPARING THE SAME, AND NITRIDE SEMICONDUCTOR COMPONENT USING THE SAME

摘要

A luminescent component which has a phosphor substrate having at least one element belonging to Group 13 (IUPAC 1989) and comprising a nitride represented by the general formula: XN wherein X is at least one element selected from among B, Al, Ga and In, a nitride represented by the general formula: XN:Y wherein X is at least one element selected from among B, Al, Ga and In, and Y is at least one element selected from among Be, Mg, Ca, Sr, Ba, Zn, Cd and Hg, or a nitride represented by the general formula: XN:Y, Z wherein X is at least one element selected from among B, Al, Ga and In, Y is at least one element selected from among Be, Mg, Ca, Sr, Ba, Zn, Cd and Hg, and Z is at least one element selected from among C, Si, Ge, Sn, Pb, O and S; and a method for preparing the luminescent component which comprises preparing the phosphor substrate by using supercritical ammonia, and forming a luminescent element on the substrate through vapor phase growth. The luminescent component has a wave length distribution for emitting a white light, and the like, and can be prepared in good yield.
