The cell tested has the Al pattern shown in Fig. 1 on the
top (anode) side and a back Al metal layer on the bottom side.
The IV curve before stressing is also shown in Fig. 3, and the corresponding EL image is shown in Fig. 4a.
Fig. 5a shows an EL image of a cell with the guard ring floating.
On the other hand, Fig. 5b shows an EL image of the same cell with 0 V applied to the guard ring.
This was confirmed from the patterns of the EL emission (Fig. 7).

We studied the EL of this
diode at high injection (10kA.cm-2) (Fig 1).
The blue free-to-bound luminescence is due to Al acceptors and N donors [7].
None of the diodes exhibited any change in the IV curves neither on the EL analysis, these diodes look like free of defects.
The EL images under forward bias confirm the importance of etching conditions.
Moreover, as was shown by Sumakeris et al., SFs can emanate from a polish scratch on the surface, a scratch made by a tip or by a wire bounding.

The electrochemical, optical, photoluminescent (PL) and electroluminescent (EL) properties of the copolymers were studied.
Y Cao et al. [5] compared the photo-electrical and electro- luminescence properties of the PFO-DBT copolymer and the blend of PFO and DBT.
Electroluminescent properties A single layer device was fabricated in the configuration: ITO/ PEDT/PFO-DBT/Ba/Al.
The EL spectra from such device are presented in Fig. 3.
EL peaks are 8-14 nm blue shifted in comparison with that of PFO-DBT15.

The effect of increasing the Mg content is well known and has previously been reported by Apelian et al.,[6] Ravi et al.,[7] and Kashyap et al.[8].
Iron and Mn were added in the form of Al-25%Fe and Al-25%Mn master alloys, respectively.
For Mg-content 319 alloys, the solution heat treated (SHT) condition show the highest elongation (El %).
This is in agreement with Samuel et al [11].
Magnesium content, Sr- modification and Aging parameters (Temperature and Time) to acquire an understanding of the effects of the variables and their interactions on the yield strength (YS) at 0.2% offset strain, ultimate tensile strength (UTS), and fracture elongation (El%) of Al-Si Mg-Cu 319 alloys.

The dynamic response of the composite soil nailed wall is analyzed and discussed under the EL-Centro and man-made Lanzhou accelerogram.
Sherif Hanna, Ilan Juran et al. have studied the design of the soil nailing structure in the earthquake areas [3].
Vucetic M, Tufenkjian et al. have completed a series of centrifuge model test of soil nailing through inputting different levels of vibration model for studying antiseismic capacity[5].
EL－Centro seismic horizontal and vertical excitations are shown in Figure 2 and 3.
