The thickness of HTL, EML, ETL, LiF and Al were 30, 30, 30, 0.5 and 200 nm.
Passivation film Al:LiF Alq3 AND:DSA NPB ITO Substrate CCM Figure 1.
J-V-L characteristics (a) and Normalize EL spectra (b) of devices.
Especially, a white EL emission spectrum of White OLED with three peaks at 460,504,596nm was clearly observed.
The blue peak originated from the EL emission, whereas the green and red peaks were from the PL emission of CCM.

In 2001, Freund et al. analyzed the behavior of boost by majority and designed an robust boost algorithm that is called as BrownBoost[7].
In the experiments, we compare four margin loss based feature selection using FWL-L1 method, including exponential loss(EL), least squares loss(LSL), logistic loss(LL) and brownboost loss(BBL).

In Table 4, through , we can find that EL, LSL and LL is very closer to about classification robustness, but BBL using FWL-GD show good classification robustness because it is higher at least 0.7% than the others about classification accuracy thought .
For the SVM-RBF classifier, EL, LSL and LL methods using FWL-L1 regularization show no significant differences to classification robustness and classification accuracy in raw data, but BBL based feature selection show the better classification performance than the others.

The Mg-Al-Zn phase has many diffraction peaks, this means it presents different grain orientations.
Region 1 is the ordered Mg2Si phase, the ordered Mg-Al-Zn phase represents region 2, region 3 is Al based fcc solid solution phase, and eutectic structures which represents region 4.
