Zhengwei. Pan, University of Georgia Research Foundation Inc, DMR 0955908. White light sources based on light-emitting diodes (LEDs) have a promising future in general illumination. For indoor lighting, the white light should be warm [i.e., correlated color temperature (CCT) <4000 K] with good color rendition [i.e., color rendering index (CRI) >80]. However, no single phosphor can simultaneously satisfy the color temperature and color rendition requirements mainly due to a lack of a red spectral component in its emission spectrum. . 15 Oct 2009.
