White Light-Emitting Diodes With High Color Rendering Index and Tunable Color Temperature Fabricated Using Separated Phosphor Layer Structure

In this letter, phosphor-converted white light-emitting diodes (pc-WLEDs) were fabricated using two separated phosphor layers (B&G up/R down) that combine three color phosphors (blue, green, and red) with near-ultraviolet LED chips. The pc-WLEDs have a high color rendering index (CRI) and a tuna...
