SUBSTRATE FOR LIGHT EMITTING DIODE AND LIGHT EMITTING DIODE
A substrate for light-emitting diodes, which uses no fluorescent powder, enables formation of a good light-emitting diode element, resulting in less deterioration, transmits light of the light-emitting diode element, emits light by utilizing a part of the transmitted light, and allows the transmitted light and newly emitted light to be mixed and emitted, is provided. The substrate for light-emitting diodes of the present invention is a substrate for light-emitting diodes, obtained by stacking a single crystal layer enabling to form a light-emitting diode element thereon and a ceramic composite layer for light conversion comprising a solidified body having formed therein at least two or more oxide phases selected from a single metal oxide and a complex metal oxide to be continuously and three-dimensionally entangled with each other, wherein at least one oxide phase out of oxide phases in the solidified body contains a metal element oxide capable of emitting fluorescence.
