Obtaining Efficiently Tunable Red Emission in Ca3-δLnδWO6:Mn4+ (Ln = La, Gd, Y, Lu, δ = 0.1) Phosphors Derived from Nearly Nonluminescent Ca3WO6:Mn4+ via Ionic Substitution Engineering for Solid-State Lighting

In this work, a facile ionic substitution strategy was initiated to realize the intense red luminescence in Ca3-δLnδWO6:Mn4+ (δ = 0.1, CLnWO:Mn4+, Ln = La, Gd, Y, Lu,) phosphors evolved from lumine...
