In this paper, we described a simple method to simulate if white light emission can be obtained with two emissive materials from their EL spectra and the mixing rate of two emissions, which is calculated with EL spectra and drawing with CIE chroma diagram.
CIE coordinates of the spectrum can be expressed by Eq.2 (2) Fig.1 Stand color matching functions in CIE 1931 Fig.2 EL spectra of NPB and (t-bt)2Ir(acac) Fig.2 shows the EL spectra of NPB and (t-bt)2Ir(acac) materials obtained from organic devices with a structure of ITO/ NPB/ 2,9-dimethyl,-4,7-diaphenyl,1,10-phenanthroline (BCP)/ tris(8-quinolinolato) aluminum (Alq)/ LiF : Al and ITO/NPB/CBP : (t-bt)2Ir(acac)/ BCP/ Alq/ LiF : Al, respectively.
The CIE coordinates of EL spectra are in good accordance with the test result from PR650 spectra colorimeter.
Then the substrate with organic layers was transferred to metal evaporation chamber with the assistance of robot to evaporate 1 nm LiF layer and 100 nm Al cathode.
The CIE coordinates white light OLEDs and EL intensity rates of two materials can be predicted with this method.

Organic EL devices using these compounds as electron-transporting layer were fabricated.
Efficient organic electroluminescence (EL) was first reported in 1987 by the researchers at Kodak [3].
To evaluate the performance of these compounds as electron-transporting materials, organic EL devices having a structure of glass / indium- tin oxide (ITO) / N, N’- di (1- naphthy1)- N, N’-diphenyl benzidine (α-NPD) (50nm) / tris (8- hydroxyquiolinolato) aluminum(Ⅲ) (Alq)(30nm) /Compounds(1)-(6) (30 nm)/ LiF(0.5 nm)/Al(100 nm) were fabricated.
We examined these compounds as electron- transporting materials for organic EL devices and successfully fabricated devices with high performance.

The measurement techniques include variable-temperature PL, spectroscopic EL, spectrally-filtered EL imaging, and EBIC imaging.
The peak energy is different from the value of 2.8 eV reported by Galeckas et al. [3], but closely matches that of the better-defined peak observed by Sridhara et al. [4].
observed in both PL and EL measurements, as shown in Fig. 1 for the EL case.
It becomes submerged under Al acceptor-related features from the p+ layer in EL measurements at lower temperatures.
A peak at 2.93 eV is related to the formation of SFs using room temperature EL spectroscopy and spectrally-filtered EL imaging.
