Zusammenfassung:The present invention provides a phosphor blend for wavelength conversion and a white light emitting device using the phosphor blend. Further disclosed is a white light emitting phosphor blend comprising 0.5~18 wt % of A5(PO4)3Cl:Eu2+ (where A is at least one element selected from Sr, Ca, Ba and Mg), 0.7~14 wt of D2SiO4:Eu (where D is at least one element selected from Ba, Sr and Ca), and 68~98.5 wt % of G5EuS(WO4)2.5+1.5S:Sm (where G is at least one element selected from Li, Na and K; and s is a number between 1 and 5), based on the total weight of the phosphor blend.
