| Abstract: |
We realize a facile chromaticity tuning for the Y 3 Al 5 O 12 :Ce 3+ phosphor-in-glass (PiG) based w-LED, with the aid of a CaAlSiN 3 :Eu 2+ red phosphor layer in a remote-type stacking configuration. It was experimentally demonstrated that both the stacking order and the relative amount of red phosphor influence the electroluminescent performance of the constructed w-LED significantly, and the optimized warm w-LED exhibits admirable performance with a luminous efficacy of 93.9 lm/W, a correlated color temperature of 3346 K, a color rendering index of 77.3, and a color shift deviating from Planckian locus in D uv of 0.0034. Significantly, the red phosphor layer stacked PiG based warm w-LED presents an excellent heat resistance, endowing the device with long life-time, which may serve as a promising robust high-power indoor lighting source.
