摘要	Eu2 and Mn2 co-doped Ca8Zn(SiO 4)4Cl2 phosphors have been synthesized by a high temperature solid state reaction. Energy transfer from Eu2 to Mn2 is observed. The emission spectra of the phosphors show a green band at 505 nm of Eu2 and a yellow band at 550 nm of Mn2. The excitation spectra corresponding to 4f7-4f65d transition of Eu2 cover the spectral range of 370470 nm, well matching UV and/or blue LEDs. The shortening of fluorescent lifetimes of Eu 2 followed by simultaneous increase of fluorescent intensity of Mn2 with increasing Mn2 concentrations is studied based on energy transfer. Upon blue light excitation the present phosphor can emit intense green/yellow in comparison with other chlorosilicate phosphors such as Eu2 and Mn2 co-doped Ca8Mg(SiO 4)4Cl2 and Ca3SiO4Cl 2, demonstrating a potential application in phosphor converted white LEDs. 2011 Elsevier B.V.
