Rare-earth ions coactivated red phosphors Gd 0.2 RE 1.8 (WO 4 ) 3 (RE ¼ Eu 3+ and Sm 3+ ) were synthesized by conventional solid-state reaction using boric acid as a flux agent. The samples were characterized by X-ray diffractometer (XRD), energy-dispersive X-ray spectrometer (EDS) and luminescence
