WOLEDs and Organic Photovoltaics
For high-quality white light illumination, sources with CIE coordinates similar to that of a blackbody radiator with a CCT between 2,500 and 6,500 K, and a CRI above 80 are required.
Handbook of Visual Display Technology
However, the peak wavelength has little significance for practical purposes since two LEDs may well have the same peak wavelength but different chromaticities – i.e., the CIE coordinates are different, and hence the color perceived by an observer also differs.
Organic Optoelectronic Materials
The maximum emission peak is at a wavelength of 616 nm with additional intensity peaks at 670 and 745 nm with CIE coordinates of (0.68, 0.32), which are close to the video display standards.
Organometallics and Related Molecules for Energy Conversion
This device reached a maximum luminous efficacy of 9.0 lm/W with CIE coordinates of (0.31, 0.36).
White organic light-emitting diodes: Status and perspective
Red stars indicate the im- portant standard illuminants E and A. CIE coordinates are plotted for commonly used phosphorescent emitters together with the color space they make possible with three-color mix- ing.
Point E slightly below the Planckian locus is also referred to as a point of equal energy, corresponding to CIE coordinates of (0.33, 0.33).
