TI  - Highly Efficient Cyan-Green Emission in Self-Activated Rb(3)RV(2)O(8) (R = Y, Lu)

AB  - Phosphor-converted white-light-emitting diodes (pc-WLEDs) rely on combining a 
      near-ultraviolet (n-UV) or blue chip with trichromatic and yellow-emitting 
      phosphors. It is challenging to discover cyan-green-emitting (480-520 nm) 
      phosphors for compensating the spectral gap and producing full-spectrum white 
      light. In this work, we successfully discovered two unprecedented bright 
      cyan-green emitting Rb(3)RV(2)O(8) (R = Y, Lu) phosphors that gives emission 
      bands centered at 500 nm upon 362 nm n-UV light excitation. Interestingly, the 
      both self-activated compounds exhibit high internal quantum efficiencies (IQEs) 
      of 71% for Rb(3)YV(2)O(8) and 85% for Rb(3)LuV(2)O(8), respectively. Moreover, 
      controllable emission color can be successfully tuned from cyan-green to 
      orange-red across the warm white light region by design strategy of VO(4)(3-) --> 
      Eu(3+) energy transfer. The thermal quenching of as-prepared phosphors could be 
      effectively mitigated by this design strategy. Finally, the as-fabricated n-UV 
      (lambda(ex) = 370 nm) pumped phosphor-converted (pc) W-LED devices utilizing 
      Rb(3)RV(2)O(8) (R = Y, Lu) along with commercial phosphors demonstrate 
      well-distributed warm white light with high color-rendering index (CRI) of 91.9 
      and 93.5, and a low correlated color temperature (CCT) of 5095 and 4946 K. It 
      suggests that the both vanadate phosphors have potential applications in 
      full-spectrum pc-WLEDs.
