Highlights •A series of Eu3+ doped α- and β-BiNbO4 polymorphs were successfully synthesized in Na2SO4-K2SO4 molten-salt medium through reaction temperature control.•The phosphors have activation energy of about 0.27 eV for α-BiNbO4:0.1Eu3+ and 0.23 eV for β-BiNbO4:0.1Eu3+ sample.•The photoluminescence color can be tuned from blue to red for both BiNbO4:xEu3+ polymorphs by adjusting Eu3+ doping concentration.
