Luminescence color tuning and energy transfer properties in (Sr,Ba) 2 LaGaO 5 :Bi 3+ ,Eu 3+ solid solution phosphors: realization of single-phased white emission for WLEDs

Controllable emission tuning from bluish-green to red was achieved by Ba ²⁺ /Sr ²⁺ substitution and Bi ³⁺ → Eu ³⁺ energy transfer.
