When the Eu3, Sm3, doped, and markedly enhanced when doped luminous intensity than the Eu3, Sm3 as sensitizers, and Eu3 resonance energy transfer, effective luminous intensity of the Eu3.
When Eu3 +, Sm3 + co-doped when the emission intensity was significantly enhanced when compared to a single Eu3 + doped, Sm3 + as a sensitizer, and Eu3 + resonance energy transfer, effectively improve the Eu3 + luminescence intensity.
When Eu3, Sm3 Co doped, Eu3 doped luminescence intensity was significantly enhanced, Sm3 as sensitizer, and Eu3 resonance energy transfer, effectively improve the luminous intensity of Eu3.
