PHOSPHOR PRODUCTION METHOD AND PHOSPHOR

A method for producing a phosphor having a core-shell structure that includes: a core part formed of a crystal phase of an inorganic compound containing a metal element M constituting a luminescent center ion and aluminum; and a shell part containing at least one element selected from the group cons...

Beschreibung
Zusammenfassung:	A method for producing a phosphor having a core-shell structure that includes: a core part formed of a crystal phase of an inorganic compound containing a metal element M constituting a luminescent center ion and aluminum; and a shell part containing at least one element selected from the group consisting of boron and silicon and formed on at least a portion of a surface of the core part, the method including: mixing a raw material of the crystal phase and a raw material of the shell part; and heating the obtained mixture at a temperature at which the raw material of the shell part is liquefied, but a host crystal of a phosphor to be obtained is maintained, in which the raw material of the crystal phase contains a raw material compound having D50 in a particle diameter distribution of 0.2 to 90 µm and containing aluminum.
