Warm-white, reddish-orange and orange light generation from lithium-aluminum-zinc phosphate glass tri-doped with Sm3+, Tb3+and Eu3+

Energy Transfer and Temperature Measurement Performance for NaGd(1-x-y)TbxEuySiO4 Phosphor

“…Under ultraviolet light excitation, Eu 3+ emits red light by the 5 D 0 → 7 F J (J = 0-4) transitions. [11][12][13][14] Recently, many Tb 3+ /Eu 3+ double doped phosphors including Tb 3+ /Eu 3+ double doped La 3 Ga 5 SiO 14 , 15 Tb 3+ /Eu 3+ double doped Ca 4 La 6 (SiO 4 ) 4 (PO 4 ) 2 O 2 , 16 Tb 3+ /Eu 3+ double doped Sr 8 MgLa(PO 4 ) 7 17 and Tb 3+ /Eu 3+ double doped Y 3 Al 5 O 12 18 have been reported. Energy transfer of Tb 3+ → Eu 3+ frequently occurs in these Tb 3+ /Eu 3+ double doped phosphors, which provides an effective way to achieve luminescence enhancement and color tunable emission.…”
