CIE color coordinates

In realizing the poor film-forming property of 9,10-(diphenyl)anthracene, the Kodak group improved this property by designing a series of blue emitters based on further substituted anthracene derivatives. The chemical structures of these materials were patented in a U.S. Patent in 1999 [239], In their patent, Kodak also reported the EL data using one of these compounds as a host material and using TBP as a blue dopant (Scheme 3.62). The device structures is ITO/CuPc/NPD/anthracene compounds.5%TBP/Alq3/Mg Ag. The EL of the device showed blue emission with CIE color coordinates of (0.144, 0.196). Without the... 

In Figure 9.13c, the EL spectra of the red-light-emitting a-Si H TFT AM-PLED and PLED are shown. EL peak positions at 654 and 653 nm, and full-width-at-half-maximum (FWHM) of 101 and 105 nm were obtained, for the a-Si H TFT AM-PLED and PLED, respectively. From the obtained EL spectra, Commission Internationale de l Eclairage (CIE) color coordinates [31] were calculated for AM-PLED and PLEDs, as shown in the inset of Figure 9.13c, and were found to be (0.67, 0.33) and (0.67, 0.32), respectively. These very...
