The structures of OLED samples are ITO/CuPc(150Å)/
�
-NPD(400Å)/Alq3(200Å)/QD(10Å)/Alq3(400Å)/Al for the undoped OLED sample, and
ITO/CuPc(150Å) /
� -NPD (400Å)/ Alq3 (200Å) doped with QD /Alq3(400Å)/Al for the codoped
sample.
Figure 5 shows the electroluminescent (EL) spectra of the OLED samples.
The peak emission wavelength of the undoped OLED was found to be 527 nm with a broad band, which is similar to EL spectra of the Alq3 material .

Sherif El-Eskandarany et al [2] studied the amorphization reaction of Al50Ta50 with the aim of finding the relationship between the amount of powder to be alloyed and the degree of transformation of the starting powders while considering the Fe contamination after milling.
Experimental Procedure Powders of nominal purity of Cu (99.9%), Co (99.9%), Ni (99.7%) and Al (99.5%) were employed in the mechanical alloying experiments using different compositions for the Co-Al, Cu-Al, Ni-Al and Cu-Co systems.
XRD patterns for mechanically alloyed powders: a) Co-48.25 at%Al. b) Co-68.5 at% Al.
In that work the studied compositions were Co-50 at. % Al, Co-71.4 at.% Al, Co-76.5 at.% Al and Co-81.8 at.% Al, which corresponded to the compounds AlCo, Al5Co2, Al13Co4, and Al9Co2, respectively, in the equilibrium phase diagram [5].
