摘要

(Tb1-xMnx)(3)Al-2(Al1-xSix)(3)O-12:Ce3+ solid solution phosphors were synthesized by introducing the isostructural Mn3Al2(SiO4)(3) (MAS) into Tb3Al5O12:Ce3+ (TbAG). Under 456 nm excitation, (Tb1-xMnx)(3)Al-2(Al1-xSix)(3)O-12:Ce3+ shows energy transfers (ET) in the host, which can be obtained from the red emission components to enhance color rendering. Moreover, (Tb1-xMnx)(3)Al-2(Al1-xSix)(3)O-12:Ce3+ (x = 0-0.2) exhibits substantial spectral broadening (68 86 nm) due to the 5d 4f transition of Ce3+ and the T-4(1) (6)A(1) transition of Mn2+. The efficiency of energy transfer ((T), Ce3+ Mn2+) gradually increases with increasing Mn2+ content, and the value reach approximately 32% at x = 0.2. Namely, the different characteristics of luminescence evolution based on the effect of structural variation by substituting the (MnSi)(6+) pair for the larger (TbAl)(6+) pair. Therefore, with structural evolution, the luminescence of the solid solution phosphors could be tuned from yellow to orange-red, tunable by increasing the content of MAS for the applications of white light emitting diodes (wLED).
