چکیده انگلیسی
We report a series of color-tunable Sr3.45Y6.5O2(PO4)1.5(SiO4)4.5:Eu2+,Mn2+ (SYPSO:Eu2+,Mn2+) phosphors in this work. The photoluminescence excitation and emission spectra, lifetime, and concentration-dependent effect were investigated, respectively. The energy transfer (ET) mechanism was verified as the dipole-dipole interaction, and the ET efficiency as well as the critical distance is also estimated. The emission colors of the obtained phosphors can be tuned from green to yellow by controlling the doping content of the Mn2+ ions with the fixed Eu2+ content. These results indicate that SYPSO:Eu2+,Mn2+ can be acted as a good candidate for the application in white light-emitting diodes.
