The Tb3+ rare-earth-ion-doped Ca2Al2SiO7 material has a tetragonal phase structure that was successfully synthesized using the solid-state reaction method under optimal conditions: sintering temperature: 1280 °C; time: 60 minutes; and the B2O3 flux agent content: 4% wt. The photoluminescence spectrum of Tb3+ doped Ca2Al2SiO7 phosphor consists of narrow lines with peaks at 545, 440, 462, 494, 590, and 622 nm that correspond to 4f electronic transitions of the Tb3+ ion. The peak at 545 nm has the highest luminescent intensity. The influence of synthesis technology and the luminescent characteristics of the phosphor are presented and discussed. |
