Figure 4From: Evaluating the use of blue phosphors in white LEDs: the case of Sr0.25Ba0.75Si2O2N2:Eu2+Chromaticity diagram with MSi 2 O 2 N 2 :Eu2+phosphors. CIE 1931 chromaticity diagram with the color points of the MSi2O2N2:Eu2+ family members. The white arrow indicates the color shift of the saturated blue Sr0.25Ba0.75Si2O2N2:Eu2+ phosphor to the white due to the yellow emitting impurity phase.
