This work, focuses on spectroscopic features such as PL and Raman thermal analysis (TGA –DSC) for the nanoparticles of aluminium oxide (GS α-Al2O3) synthesizes by two plant solutions (leaves(S1) phloem(S2)) at room temperature. In different reactions, extracts are mixed with metal precursor solutions, Various reactions carried out when combined them biomolecules responsible reducing ions capping bio-reduced synthesized using extract. As a result, calcination products powder alumna 1800 ͦC...
Fast response time UV photoconductive detector was fabricated based on ZnO film prepared by thermal chemical spray pyrolysis technique. The nanofilms are grown the porous silicon (PS) nanosurface which has drastically reduced of from few seconds to hundreds microseconds. surface functionalization deposited layer polyamide nylon highly improved photoresponsivity 0.8 A/W. normalized de-tectivity (D*) at wavelength 385 nm is found be about 2.12 × 1011 cm Hz1/2 W–1. oriented in c-axis and it a...
In this work, ZnS structure change from the molecular size of Wurtzite to obtain on longitudinal mode vibrational properties for both IR and Raman intensities other features vibration like forces constant reduced masses bare H-passivation Wurtzoids nanostructures. The modes represented by Longitudinal optical (LO) structures as nanoscale with H-passivated (Hp) shifted red shift inverse blue respect bulk. theoretical study nanotubes using Ab-initio density functional theory (ADFT) comparison...
In the beginning, NiO/SnO2 nanocomposite thin film was prepared of nickel nitrate (1.5213) gm that weighed and dissolved in distilled water to obtain a specific molar concentration at room temperature as nanoparticles mixed with half mount (0.5121) SnO2, addition other steps on study some features it. The structural properties films using chemical technique studied, such XRD, FE-SEM, AFM, were found Nano-composite crystallizes are hexagonal structures an average crystallite size 16.30nm....
حظي التصنيع الحيوي للجسيمات النانوية باهتمام واسع النطاق بسبب فوائده مثل البساطة والملائمة للبيئة والسرعة والفعالية من حيث التكلفة. تم تصنيع جسيمات السيلينيوم SeO2NPs) باستخدام مستخلصات لحاء القرفة ((CVBE ورباعي كلوريد السيلينيوم. في هذه الدراسة ,تم استخدام تقنيات XRD و TEM UV FTIR لتوصيف SeO2 NPs المُصنَّع بيولوجيًا, البنية البلوريه لها تكون سداسية كما يتضح نتائج الاشعه السينية . تحقيق الحجم البلوري حوالي 24.5 نانومتر وأظهرت صورة أن قطر كان أقل 100 بشكل كروي وشبه كروي. تأثير على مضادات...
The nanocrystals of Cadmium sulfide (CdS) are synthesized via chemical bath technique and deposited onto glass substrates commercial plates at different time (60,120,180and 240 )minute respectively, then annealing 300°C to enhance the adhesion recrystallization films. results confirmed that structural features examined by X-ray diffraction(XRD) wurtzite structures for all samples while atomic force microscope( AFM ) examinations give prefect analyses proved increasing precipitation times...
Abstract The chalcogenide structures are studied at nano scale theoretically, Znic Selenium is one of these theoretically by DFT, once as a diamantane(Zn 7 Se cubic in solid state) or again diamondoids (Zn S H 14 ), where similarity formula but different from wurtziod ) stoichiometry nano-limited, the molecules ZnSe diamantane formed change size. However both spectra and electronic properties calculated. In this work, used RB3LYP/3-611 G(p,d) base set, it can note that blue shift Raman...
