Photoluminescence energy transfer is a good strategy to enhance the efficiency or tuning of emission colors. A phosphor host containing Gd3+ may facilitate the host-sensitization effect and transfer the so-absorbed photon energy to other activators. Zn1−xMnxGdB5O10 (0.005 ≤ x ≤ 0.07), ZnGd1−yDyyB5O10 (0.01 ≤ y ≤ 0.09), and ZnGd1−zSmzB5O10 (0.01 ≤ z ≤ 0.09) were synthesized via the traditional high-temperature solid-state method. A powder X-ray diffraction technique was employed to confirm the phase purity and successful doping. In all phosphors, by monitoring the characteristic emission of Mn2+, Dy3+ and Sm3+, the excitation spectra of all were found to contain the typical absorption belonging to Gd3+; in addition, the largely shortened fluorescence lifetimes of Gd3+ after Mn2+, Dy3+ or Sm3+ doping strongly proved the existence of the host-sensitization effect. Along with Gd3+-sensitization, Mn2+ doped at the Zn2+ site emits a close-to-ideal red light. Dy3+ and Sm3+ doped at the Gd3+ site emit close to white and orange light, respectively. The calculated internal quantum efficiency is 25.5% for Zn0.995Mn0.005GdB5O10, 17.0% for ZnGd0.97Dy0.03B5O10 and 17.4% for ZnGd0.97Sm0.03B5O10. The high thermal stability of the photoluminescent emission for Mn2+, Dy3+, and Sm3+ can be demonstrated through in situ high-temperature experiments, which suggest possible enhanced energy transfer efficiency at high temperatures.
