Controllable photoluminescence enhancement of CdTe/CdS quantum dots thin films incorporation with Au nanoparticles
Au nanoparticles (Au NPs)/CdTe/CdS QDs nanocomposite films were fabricated by deposition of Au NPs and layer-by-layer self-assembly of colloidal CdTe/CdS QDs. Photoluminescence (PL) spectra showed that Au NPs incorporation resulted in an increase of PL intensity about 16-fold compared with that of the samples without Au NPs. PL enhancement of Au NPs/CdTe/CdS QDs nanocomposite films can be contr...
متن کاملEffect of growth time on ZnO thin films prepared by low temperature chemical bath deposition on PS substrate
ZnO thin films were successfully synthesized on a porous silicon (PS) substrate by chemical bathdeposition method. X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM),and photoluminescence (PL) analyses were carried out to investigate the effect of growth duration(3, 4, 5, and 6 h) on the optical and structural properties of the aligned ZnO nanorods. T...
متن کاملCorrelation between crystal structure and optical properties of copper- doped ZnO thin films
ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...
متن کاملPreparation and Characterization of Polyaniline/ZnO Composite Sensor
Polyaniline/ZnO nanocomposite thin films were prepared via an electrochemical synthesis route on ITO coated glass substrates. ZnO nanoparticles were uniformly dispersed in to the polyaniline matrix. Interaction between ZnO nanoparticle and polyaniline has been studied using X-ray diffraction (XRD), UV-Vis absorption spectroscopy, PL spectroscopy, AFM and I-V characteristics. The ammonia gas sen...
متن کاملDMMP Sensing Performance of Undoped and Al Doped Nanocrystalline ZnO Thin Films Prepared by Ultrasonic Atomization and Pyrolysis Method
Highly textured undoped (pure) and Al doped ZnO nanocrystalline thin films prepared by ultrasonic atomization and pyrolysis method are reported in this paper. ZnCl2 water solution was converted into fine mist by ultrasonic atomizer (Gapusol 9001 RBI Meylan, France). The mist was pyrolyzed on the glass substrates in horizontal quartz reactor placed in furnace. The Structural and microstructural ...
