Luminescent properties of HTP AgGd1−xW2O8:Eux3+ and AgGd1−x(W1−yMoy)2O8:Eux3+ phosphor for white LED

► Tetragonal/monoclinic phases AgGdEuW2O8 are synthesized at different temperatures. ► Luminescent properties of two kinds of structures AgGd1−xEuxW2O8 are discussed. ► Doping of Mo6+ in AgGd1−xEuxW2O8 enhanced luminescent intensities obviously.
