ABSTRACT:
Provided, among other things, is a phosphor according to the formula:in-line-formulae description="In-line Formulae" end="lead"?[(BvSiO3)x(Mv2SiO3)y(Tv2(SiO3)3)z]m•(SiO2)n: Rε, X (I)in-line-formulae description="In-line Formulae" end="tail"?wherein x, y and z are any value such that x+y+z=1; Bv is one or more divalent alkaline earth metals; Mv is one or more monovalent alkaline metals; Tv is one or more trivalent metal ions; Rε is one or more activators selected from Eu2+and Mn2+; X is one or more halides; m is 1 or 0; and (i) n>3 if m=1 and provides an amount of silica effective to host useful luminescence or (ii) n=1 if m=0.
