Abstract
To realize a high luminous efficacy and a high emission color purity for the white-LEDs, the understanding for luminescence properties of the phosphors is significantly important because the performance of white-LEDs is directly affected by the luminescence properties of the phosphors. In this paper, therefore, we reviewed some commercially available $Eu^{2+}$- and $Ce^{3+}$- activated phosphors and discussed for the luminescence properties of these phosphors.
Key Words: White LEDs, Luminescence properties, Oxide phosphor, (Oxy)Nitride phosphor, Phosphor in glass (PIG)
