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 A<SUB>5</SUB>(PO<SUB>4</SUB>)<SUB>3</SUB>Cl:Eu<SUP>2+</SUP> (where A is at least one element selected from Sr, Ca, Ba and Mg), 0.7~14 wt of D<SUB>2</SUB>SiO<SUB>4</SUB>:Eu (where D is at least one element selected from Ba, Sr and Ca), and 68~98.5 wt % of G<SUB>5</SUB>Eu<SUB>S</SUB>(WO<SUB>4</SUB>)<SUB>2.5+1.5S</SUB>: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.
