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 Eu<sup>3+</sup> and Sm<sup>3+</sup> doping, indicating that the phosphor can correlate well with LED chips. Under violet light excitation of 394nm the phosphor Eu<sup>3+</sup>&nbsp;doped Sr<sub>3</sub>La(AlO)<sub>3</sub>(BO<sub>3</sub>)<sub>4 </sub>and of 406&nbsp;nm the phosphor Sm<sup>3+</sup>&nbsp;doped Sr<sub>3</sub>La(AlO)<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub> can emit strong red light showing main emission peaks located at 617&nbsp;nm and 602&nbsp;nm are observed respectively. The PL properties implies the excellent stability of the phosphor. These results imply that the importance red phosphors Sr<sub>3</sub>La(AlO)<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub>:Eu<sup>3+ </sup>&nbsp;and Sr<sub>3</sub>La(AlO)<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub>:Sm<sup>3+</sup>&nbsp;in W-LEDs under NUV excitation.</p> ER -
