ABSTRACT:
A light conversion structure ensuring good light transmission and less deterioration and capable of controlling light to a desired color tone and emitting a highly bright light, and a light-emitting device using the same. The light conversion structure is a light conversion structure including a layer formed of a ceramic composite, which absorbs a part of a first light to emit a second light and transmits a part of the first light, and a fluorescent layer for the control of color tone, which is formed on the surface of the ceramic composite and which absorbs a part of the first light or a part of the second light to emit a third light and transmits a part of the first light or a part of the second light, wherein the ceramic composite includes a solidified body where at least two or more metal oxide phases are formed continuously and three-dimensionally entangled with each other, and at least one metal oxide phase in the solidified body includes a metal element oxide capable of emitting fluorescence.
