The controlled synthesis of Fe0.5Gd0.5(MoO4)1.5:Eu3+ microcrystals (self-aggregated 3D superstructures) using hydrothermal method by employing PVP as surfactant along with the state of the art of this field at present. By varying the reaction time, we have reported the morphology selection and the condition to derive novel nanoparticle sheathed bipyramid-like morphology. The rest of the parameters like, molar ratio between initial precursor / surfactant and temperature were kept as constant. The Fe0.5Gd0.5(MoO4)1.5:Eu3+ microcrystals are found to be an excellent matrix for photoluminescence property and the Eu3+ ion serves as a good red emitting luminescent center. Further, room temperature (RT) magnetic properties of Fe0.5Gd0.5(MoO4)1.5:Eu3+ were investigated in detail.
