Abstract
The La<sub>3</sub>Ga<sub>5</sub>SiO<sub>14</sub> based phosphors were generated by substitutions of Tb<sup>3+</sup>/Eu<sup>3+</sup> to La<sup>3+</sup>. The Tb<sup>3+</sup> → Eu<sup>3+</sup> energy transfer occurs in Tb<sup>3+</sup>/Eu<sup>3+</sup> codoped phosphors. The La<sub>2.70</sub>Eu<sub>0.12</sub>Tb<sub>0.18</sub>Ga<sub>5</sub>Si<sub>14</sub> phosphor shows an internal quantum yield about 88.82%.
