Provided is a ceramic complex for light conversion that can lengthen a fluorescent dominant wavelength to 580 nm and can arbitrarily adjust the wavelength within a range of 570 to 580 nm, in which the fluorescent light intensity is not reduced even though the wavelength is lengthened, and that suppresses variation in light emittance. Further provided is a ceramic complex for light conversion with excellent heat resistance and suitable for increased output of a white-light-emitting device. Further provided is a light-emitting device that uses this ceramic complex for light conversion. The present invention is a ceramic complex for light conversion, which is a solidified material made from a composition expressed by formula (1) having an organization where at least two oxide phases, a first phase and a second phase, are continuously, three-dimensionally, and mutually entangled; wherein the first phase is a (Tb, Y)3Al5O12 phase activated by Ce that emits fluorescent light, and the second phase is an Al2O3 phase. |
