[Display omitted] • Synthesis of Tb3+/Eu3+ doped Bi 2 Sn 2 O 7 phosphors. • Energy transfer in Tb3+/Eu3+ doped Bi 2 Sn 2 O 7 phosphors. • Tunable luminescence of Tb3+/Eu3+ doped Bi 2 Sn 2 O 7 phosphors. Tb3+/Eu3+ doped Bi 2 Sn 2 O 7 phosphors were synthesized by a co-precipitation method. XRD patterns indicate that Tb3+/Eu3+ doped Bi 2 Sn 2 O 7 have a single phase. TEM images indicate that the phosphors are irregular particles with the size of several nanometers. Tb3+ or Eu3+ singly doped Bi 2 Sn 2 O 7 phosphors show characteristic photoluminescence of Tb3+/Eu3+ ions while they are excited. And Tb3+/Eu3+ codoped Bi 2 Sn 2 O 7 phosphors show tunable photoluminescence because of Tb3+ → Eu3+ energy transfer. The light can move from green region to yellowish-red region via yellow region by changing Eu3+ concentration. [ABSTRACT FROM AUTHOR]
