Abstract
A compound, according to general formula 1: M(II)Ln(III)
1-p-q
Ce(III)
p
Tb(III)
q
M'(III)
3
O
7
wherein M(II) represents a divalent metal selected from the group of Ca, Sr and mixtures thereof; Ln(III) is a trivalent metal selected from the group consisting of Y, Gd, La, Lu and mixtures thereof; M' (III) is another trivalent metal selected from the group consisting of Al, Ga and mixtures thereof; and wherein p and q represent fractional numbers varying between 0 and 1, and1≥p+q>0 is provided. M' (III) may be substituted by a tetravalent component M''' (IV), in which case the trivalent metal M' (III) may be substituted with a divalent metal M'' (II) or the divalent metal M(II) may be substituted with a monovalent metal M'''' (I) to maintain charge balance. The compounds of formula 1 can find use as phosphors including in lighting applications.
