A phosphor material is presented that includes a blend of a first phosphor, a second phosphor and a third phosphor. The first phosphor includes a composition having a general formula of RE 2-y M 1+y A 2-y Sc y Si n-w Ge w O 12+δ : Ce 3+ wherein RE is selected from a lanthanide ion or Y 3+ , where M is selected from Mg, Ca, Sr or Ba, A is selected from Mg or Zn and where 0≤y<≤2,, 2.5≤n≤3.5, 0≤w≤1, and -1.5≤δ≤1.5. The second phosphor includes a complex fluoride doped with manganese (Mn 4+ ), and the third phosphor include a phosphor composition having an emission peak in a range from about 520 nanometers to about 680 nanometers. A lighting apparatus including such a phosphor material is also presented. The light apparatus includes a light source in addition to the phosphor material. |
