Abstract

A Red emitting with high efficiency Eu3+ doped Sr3La(AlO)3(BO3)4 and Sm3+ doped Sr3La(AlO)3(BO3)4 phosphors  has been synthesized by combustion method, meanwhile, the photoluminescence properties of samples are investigated in detail. Morphology by SEM and chromaticity by CIE was studied. The results show that the excitation extends from 340 nm to 420 nm, with the highest excitation (394 nm and 406 nm) being in the violet area for Eu3+ and Sm3+ doping, indicating that the phosphor can correlate well with LED chips. Under violet light excitation of 394nm the phosphor Eu3+ doped Sr3La(AlO)3(BO3)4 and of 406 nm the phosphor Sm3+ doped Sr3La(AlO)3(BO3)4 can emit strong red light showing main emission peaks located at 617 nm and 602 nm are observed respectively. The PL properties implies the excellent stability of the phosphor. These results imply that the importance red phosphors Sr3La(AlO)3(BO3)4:Eu3+  and Sr3La(AlO)3(BO3)4:Sm3+ in W-LEDs under NUV excitation.
