N2 - Abstract: In this paper, green-blue emitting Sr 2 SiO 4 (SSO):0.03Tb 3+ , xCe 3+ (x = 0–0.005) materials were synthesized via a solid-state reaction method. The crystal structures, luminescence properties, decay time, and thermal stability were measured in this work. The as-prepared phosphors exhibit both an indigo emission of Ce 3+ and green emission of Tb 3+ with considerable intensity (λ ex = 300 nm). Tb 3+ ion emission was intensified obviously with co-doping Ce 3+ . The luminescence spectra of Sr 2 SiO 4 (SSO):0.03Tb 3+ , Ce 3+ shows characteristic line of Tb 3+ ion transition ( 5 D 4 → 7 F 5 ). Tunable green-blue color can be obtained by the addition of Ce 3+ ions. An effective energy transfer process between Tb 3+ and Ce 3+ was supposed and confirmed from decay curves. In addition, the energy transfer mechanism from Ce 3+ to Tb 3+ ions in the Sr 2 SiO 4 (SSO) host is electric multipolar interaction. Sr 2 SiO 4 (SSO):Tb 3+ , Ce 3+ phosphor exhibits good thermal stability, the quantum yield was about 43.67%, indicating a potential candidate for solid-state lighting. Graphical Abstract: Sr2SiO4:Tb 3+ , Ce 3+ phosphor can obtain tunable green-blue emission based on the energy transfer between Ce 3+ and Tb 3+ ion. Almost 90% of the luminescence intensity of SSO:0.03Tb 3+ , 0.003Ce 3+ phosphor was retained after an increase in temperature to 200 °C.[Figure not available: see fulltext.].
