蛍光体前駆体組成物
Document Type and Number:
Japanese Patent JP2014523952
Kind Code:
A
Abstract:
In accordance with one aspect of the present invention, a phosphor precursor composition is provided. The phosphor precursor composition includes gamma alumina, strontium oxide precursor, europium oxide precursor, and an alkaline earth metal precursor other than strontium oxide precursor which affords a phosphor having a formula selected from the group consisting of Sr4Al14O25:Eu2+, Sr4-a-zAaEUzAl14O25, and combinations thereof upon thermal treatment at a temperature above 800° C., wherein A is an alkaline earth metal other than strontium, 0≰a<4; 0.0010. Another aspect of the present invention provides a phosphor composition. Also provided in another aspect of the invention is a method of making the phosphor and a lighting apparatus including the phosphor.
