Fabrication and EL measurements of OLEDs.
The evaporating rates were kept at 0.5-1Å s-1 for organic layers and LiF layer, and 10Å s-1 for Al cathode, respectively.
EL spectra were measured with a Hitachi MPF-4 fluorescence spectrophotometer.
EL properties.
The EL spectra centered at 550nm show broad EL emission with the full width of half maximum of 105nm and hypsochromic shift compared with PL spectrum probably due to the solvatochromism [18].

In agreement with the results found by Madey et al., we think that Pt coverage in access of 1.1 ML have formed 3D islands [13].
Indeed, it was observed by El Jawad et al. [12] that a minimal coverage of 2.2 monolayers is necessary to ensure the stability of the Pt/W(111) electrode in acidic electrolyte.

Physical Simulation of Thermo-Mechanical Processing of Ferritic-Bainitic Dual Phase (FBDP) Steel Taher El-Bitar1, Eman El-Shenawy1,* and Maha El-meligy1 1Plastic Deformation Department, Central Metallurgical R&D Institute (CMRDI), Egypt Keywords: Ferrite, Bainite, Dual Phase, FBDP, high strength steel, automotive industries, Gleeble 3500 Abstract: The present work is dealing with a physical simulation of thermo-mechanical processing of ferritic-bainitic dual phase (FBDP) steel alloy containing 0.1% C, 0.3% Si, 0.9% Mn and 0.7% Cr.
Kumar et al.[5] investigated microstructural characteristics of FBDP steels with 60 to 70% bainite, and found that the steel possessed an excellent combination of strength and ductility.
Recently, Podder et al. [6] reported that a small amount of martensite (2% and above) is sufficient to produce continuous yielding, high tensile strength, and adequate ductility in FBDP steels.
