Eu3+/Tb3+ co‐doped borophosphate glass was synthesized by a melt‐quenching method for the luminescence color‐tunable performance. Under the excitation of 373 nm, the Tb3+‐doped glass exhibited a very strong green emission at 544 nm, corresponding to the electron transition 5D4→7F5 of Tb3+. The emission intensity and lifetime of 5D4 level of Tb3+ dropped with the increase of Eu3+ co‐doping, whereas...
