Color-tunable white-light emitting BaMg2Al6Si9O30：Eu2＋,Tb3＋,Mn2＋ phosphors via energy transfer（Invited）
摘要
Abstract
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.关键词
