Abstract

In this study, there are two objectives had been done. The first involved the fabrication of a white light emitting diode (LED) with a high color rendering index (CRI) through the near-ultraviolet excitation of red, green, and blue phosphors, and the phosphor ratios were adjusted to obtain a color temperature of 2800 K. Due to this LED had relatively low brightness, the addition of gold nanoparticles at various concentrations had been done to enhance light reflection within the LED, thereby improving the light output. The nanoparticle diameters were measured through high-resolution transmission electron microscopy, and the chromaticity coordinates, CRI, luminous flux, and radiation power of the light source were measured using an integrating sphere. Finally, a white LED with a high CRI and a high light intensity was successfully developed.
