Abstract:
A complex crystal phosphor is an inorganic composition containing at least an M element, an Al element, silicon, oxygen, and nitrogen. The inorganic composition has particles having at least two types of crystal phase, and the at least two types of crystal phase include a first crystal phase which is the same as a M2SiO4 crystal and a second crystal phase as a β-sialon crystal. Here, M is at least one element selected from the group consisting of (Mg), calcium (Ca), strontium (Sr), and barium (Ba).
