Tunable concentration/excitation-dependent deep-red and white light emission in single-phase Eu2+-activated Sc-based oxide phosphors for blue/UV-LEDs

Novel Sr 3 Sc 4 O 9 : x Eu phosphors with tunable luminescence are firstly reported. All experimental results suggest the utilization potentiality of the multifunctional Sr 3 Sc 4 O 9 : x Eu phosphors in agricultural and full-spectrum general lighting.
