  • Single-phase white-light emitting phosphors BaMg2Al6Si9O30∶ Eu2+,Tb3+,Mn2+ are synthesized by solid state reaction. The energy transfers from Eu2+ to Tb3+ and Eu2+ to Mn2+ in BaMg2Al6Si9O30 are demonstrated by fluorescent spectra, energy transfer efficiency and fluorescent life time analysis. The BaMg2Al6Si9O30∶ Eu2+,Tb3+,Mn2+ shows three emitting colors: 450, 542 and 610 nm, which are assigned to the contribution from Eu2+, Tb3+ and Mn2+, respectively. By tuning the relative composition of Tb3+/Mn2+, chromaticity coordinates of (0.31, 0.30), color rendering index Ra=90 and Correlated Color Temperature(CCT) of 5 374 K can be achieved upon the excitation of UV light. Experimental results indicate that the present phosphor BaMg2Al6Si9O30∶ Eu2+,Tb3+,Mn2+ can serve as potential candidates for light emitting diodes.
