Correlation Between Surface Morphology and Optical Properties of Quasi-Columnar Porous Silicon Nanostructures
In the current work, the effect of surface morphology on light emission property and absorption behavior of quasi-columnar macro-porous silicon (PS) was investigated. PS structures with different morphology were synthesized using photo-electrochemical etching method by applying different etching current densities. SEM micrographs showed that empty macro-pores size and porosity of PS layers were...
متن کاملInfluence of hydrogel polymer and NO3-: NH4+ ratios on dill (Anethum graveolens L.) seed essential oil composition and yield
To evaluate the effects of hydrogel polymer levels (0, 10, 20, 30 g m-2) and NO3:NH4 ratios (0: 100, 25: 75, 50: 50, 75: 25, and 100: 0) on dill seed yield and its essential oil constituents, an experiment was conducted in October 2012 in the experimental field of Islamic Azad University, Jiroft, Iran. Results showed that using 30 g m-2 hydrogel polymer with 75NO3-: 25 NH4+ ratio produced ...
متن کاملTuning the Luminescence of CdS Quantum Dots by a Simple Method
In this report, we present a facile approach for the synthesis of luminescent CdS and CdS:Mn+2 nanocrystals by reaction of CdSO4 and Na2S2O3 in the presence of thioglycerol (C3H8O2S) as capping agent. The influence of various experimental variables including, pH values and percentage of dopant, on the growth...
متن کاملMorphology and Mechanical Properties Investigation of Binary Polymer Blends Based on PP/SEBS and PP/PC
In this study, eight binary blends of polypropylene (PP)/ poly [styrene-b-(ethylene-co butylene)-b-styrene] tri-block copolymer (SEBS) and polypropylene (PP)/ polycarbonate (PC) were produced at different composition through twin screw extruder. The composition of the minor phases was changed to correlate the morphology and mechanical properties of binary blends (PP/PC and PP/SEBS) through ther...
متن کاملFabrication Of Cu(In,Ga)Se2 Solar Cells With In2S3 Buffer Layer By Two Stage Process
Cu(In,Ga)Se2 thin films (CIGS) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of Co-evaporated metallic precursors in Se-containing environment under N2 gas flow. Structural properties of prepared thin film were studied. To characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...
