Using the solid-state technique that involves great temperature, we created multiple phosphors Sr<sub>4</sub>La(PO<sub>4</sub>)<sub>3</sub>O:Ce<sup>3+</sup>, Tb<sup>3+</sup>, Mn<sup>2+</sup> (abbreviated as SLPO:Ce, Tb, Mn). We then examined their heat consistency, luminescence, well energy shift from Ce<sup>3+</sup> to Tb<sup>3+</sup> and Mn<sup>2+</sup>. can acquire a considerable boost for faint emission in green generated by red via adding sensitizer ions. Through modifying proportion between along with Mn<sup>2+</sup>, it is possible adjust chroma of emission. acquired white illumination which had color coordinates determined (0.3326, 0.3298) testing phosphor Sr<sub>4</sub>La(PO<sub>4</sub>)<sub>3</sub>O: 0.12Ce<sup>3+</sup>, 0.3Mn<sup>2+</sup>. Such result displays promising efficiency WLED devices.
