- BAM E When u phosphor was examined, it was hardly observed below 850 ° C, but increased sharply above 1000 ° C. The reason why the valence change of Eu does not appear until the temperature exceeds 100 ° C. is as follows.
- the vacancy surrounding the Eu in the host crystal Since this requires the movement of atoms in the host crystal, this reaction requires a high temperature exceeding 100 ° C., which is equivalent to crystal growth.
- Sr may not be included in the composition of the phosphor, but when Sr is included, a part of Ba "is replaced by Sr" having a smaller ionic radius, and the crystal structure is reduced. By slightly reducing the lattice constant, the emission color of the blue phosphor can be made closer to a more desirable color.
