CERAMIC COMPLEX, LIGHT EMITTING DEVICE, AND METHOD FOR PRODUCING CERAMIC COMPLEX
A ceramic complex including a first crystal phase containing a first rare earth aluminate fluorescent material containing an activating element and a first rare earth element that is different from the activating element, and a second crystal phase containing aluminum oxide, having a content of the first crystal phase in a range of 5% by volume or more and 40% by volume or less and a content of the second crystal phase in a range of 57% by volume or more and 95% by volume or less based on a total amount of the ceramic complex, having an average value of a second crystal diameter of the second crystal phase measured under the particular measurement condition of 12 μm or less, and having a QD value of 0.5 or less expressed by QD=(D75−D25)/(D75+D25), wherein D25 and D75 are defined in the disclosure.
