Study of red-emitting LaAsO4:Eu3+ phosphor for color
rendering index improvement of WLEDs with dual-layer remote phosphor geometry
The remote phosphor structure is often disadvantageous in color quality but in terms of optics it is more convenient when compared to other phosphor structures such as conformal or in-cup ones. From this disadvantage, there are many studies to…

Improving color rendering index of WLEDs with convex-dual-layer remote phosphor geometry using red-emitting CaGa2S4:Mn2+ phosphor
The white-light light-emitting diode (LED), a conventional illumination
solution, usually consists of one chip and one phosphor layer, which leads to the insufficient color rendering index (CRI) in this configuration. To optimize the efficiency of…

The application of dual-layer remote phosphor geometry in achieving higher color quality of WLEDs
If remote phosphor structures are put into comparison with conformal
phosphor or in-cup phosphor, their luminous flux are better, but the color
quality is not as elevated. This leads to an obvious need of a practical
solution to enhance color…
