Abstract  Y$_{0.75 - x}$GdxAl0.10BO3:Eu$^{3+}_{0.10}$, 0.05R3+ (= Sc, Bi)  (0.00 ≤ x ≤ 0.45) powder samples are prepared by solid-state reaction and their luminescence properties are investigated. With the replacement of Y3+ ions by Sc3+ (or Bi3+) and Gd3+ ions in (Y, Al)BO3:Eu, the intensities of emission at 254 and 147~nm are remarkably improved, because Sc3+ ions can absorb UV light and transfer the energy to Eu3+ ions efficiently. Moreover, Gd3+ and Bi3+ ions act as an intermediate ``bridge'' between the sensitizer and the activator (Eu3+) in energy transfer to produce light in the (Y, Gd)BO3:Bi3+, Eu3+ system more effectively. After doping an appropriate concentration of Gd3+ into Y$_{0.50}$Gd$_{0.25}$Al0.10BO3:Eu$^{3+}_{0.01}$, Bi$^{3+}_{0.05}$, the emission intensity reaches its maximum, which is nearly 110{\%} compared with the red commercial phosphor (Y,Gd)BO3:Eu and better chromaticity coordinates (0.650, 0.350) are obtained.
