Abstract

A combination of fluorescent SiC (f-SiC) and porous f-SiC is a promising phosphor material for pure white light emission. Herein, the anodic oxidation condition is optimized to produce porous f-SiC. Furthermore, a hybridly packaged white light emitting diode (LED) package composed of f-SiC/porous f-SiC stacks with a nitride-based NUV-LED as an excitation source is fabricated. A distinct pure white light emission and the peak luminous efficacy of 11.6 lm W⁻¹ at a forward current of 10 mA in the NUV-LED are observed. At the peak luminous efficacy, the estimated internal quantum efficiency of the f-SiC/porous f-SiC stacks is ≈80% as the package involved several types of optical and energy losses.
