The influence of Eu3+ doping on photoluminescent properties of red emitting phosphor YInGe2O7:Eu3+ by microwave assisted and conventional sintering method

► Microwave promotes sintering of YInGe2O7:Eu3+ phosphors. ► The microwave sintered YInGe2O7:Eu3+ phosphors have more uniform grain size. ► The concentration quenching was observed under microwave sintering conditions. ► Microwave processing has potential to reduce the time, cost, and required energy.
