• GdVO4:Eu3+ phosphors have been efficiently synthesized by a SMC method.
• Bi3+ can be encapsulated into the phosphor.
• The doping concentration and pH dependence were discussed.
GdVO4:Eu3+, Bi3+ with tetragonal phase has been successfully synthesized by employing efficient irradiations. The assembly of composites with fine grains based on acoustic energy and microwave radiation requires low temperature (90 °C) and short reaction time (60 min). All the compounds exhibited red emissions and they can be sensitized through the doped Bi3+ ions. The dependence of pH changes and doping concentration on the fluorescence features has been discussed. The photoluminescence measurements show that the optical properties achieved the best results at pH = 9 for GdVO4:Eu3+(5 mol%), Bi3+(1 mol%) or pH = 7 for GdVO4:Eu3+.
