Abstract

Dy3+/Eu3+ions co-doped Ca7Si2P2O16phosphors were successfully prepared by the sol-gel method. The characterization results confirmed that the rare earth ions occupied Ca2+sites in Ca7Si2P2O16crystal. Meanwhile, the luminescent properties of Ca7Si2P2O16:Eu3+, Dy3+upon excitation at 361 nm were discussed and its sharp emissions were in blue and red spectral regions, respectively. The luminescence intensity and CIE varied with the doping ratio of Dy3+, Eu3+and the emission region is close to the white light. All the results showed that Ca7Si2P2O16: Dy3+, Eu3+as a single host phosphor could be applied in the field of UV-excited white LEDs. [ABSTRACT FROM PUBLISHER]
