•Single Bi3+ and Dy3+ co-doped YBO3 phosphors at low temperature (900 °C) are prepared.•The energy transfer from Bi3+ to Dy3+ is dependent on the concentration of Bi3+ ion.•The spectrum overlaying provides condition to the resonance energy transfer.•The luminescence of Bi3+ and Dy3+ co-doped YBO3 phosphors were reported.
Bi3+ and Dy3+ co-doped YBO3 phosphors were successfully synthesized by solid-state-reaction method at 900 °C. The co-doping of Bi3+ and Dy3+ into YBO3 results in enhanced yellow emission band while the blue emission band remains relatively unchanged. The emission intensities of the studied materials were investigated as a function of different Bi3+ ion concentrations. The results show that they could be efficiently excited by UV light of 270 nm, indicating a potential application for the phosphors in the fluorescent lamps.
