## Abstract Eu^3+^, Bi^3+^ coactivated doubleβtungstate phosphors were prepared by the solidβstate reaction technique, and their photoluminescent properties were investigated. No concentration quenching of Eu^3+^ was observed in the series samples of NaLa~1β__x__~ (WO~4~)~2~:__x__ Eu^3+^. With the
Rare-earth ions coactivated red phosphors Gd 0.2 RE 1.8 (WO 4 ) 3 (RE ΒΌ 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
The photoluminescent (PL) properties of new red-emitting praseodymium-activated strontium indates have been investigated. A series of SrIn 2 O 4 : x Pr 3Ψ (x β«Ψβ¬ 6.25 Ψ 10 Ψ 4 , 0.5%, 2%, and 4%) phases were synthesized and found to exhibit red emission. With di4erent levels of Pr 3 Ψ doping, the ab
