Characterization of MWCNT-TiO2 Qps and TiO2 QDs in self-assembled films
Akkaya Arier, Ümit Özlem; Uysal, Bengü Özuğur (Elsevier, 2017)In this study the solution which includes TiO2 quantum dots (QDs) was mixed with the multi-wall carbon nanotubes (MWCNTs) to prepare MWCNT-TiO2 QDs composite films. The effect of microstructures on the structural and optical ... -
Controlling the growth of particle size and size distribution of silica nanoparticles by the thin film structure
Uysal, Bengü Özuğur; Tepehan, Fatma Zehra (Springer, 2012)Nanostructured silicondioxide thin films were prepared by sol-gel spin coating technique. The SiO2 films were made using a conventional mixture of tetraethoxysilane (TEOS) deionized water and ethanol with various NH3/TEOS ... -
Determination of growth kinetics and size dependent structural morphological optical characteristics of sol-gel derived silica nanoparticles in silica matrix
Uysal, Bengü Özuğur; Tepehan, Fatma Zehra (De Gruyter Poland Sp Zoo, 2019)Nanocomposite silica thin films made using the sol-gel method were studied. The nano-silica films were prepared using a mixture of tetraethyl orthosilicate (TEOS) deionized water ethanol and ammonia solution. To control ... -
The effects of Dea:water ratio on the properties of ZnO nanofilms obtained by spin coating method
Akkaya Arier, Ümit Özlem; Uysal, Bengü Özuğur (Elsevier Science, 2014)In this work the ZnO were fabricated with the sol-gel spin coating method and the effects of the Dea:water ratios on the properties of the as-prepared ZnO thin films were determined by using a X-ray diffractometer transmission ... -
Effects of Precursor Parameters on the Optical and Electrical Properties of AZO Nano-Composite Films
Akkaya Arier, Ümit Özlem; Uysal, Bengü Özuğur (Elsevier GMBH Urban & Fischer Verlag, 2016)Al doped ZnO (AZO) nano-composite films were synthesized on glass substrates with the sol gel spin coating method at the room temperature. The activation energy of AZO nano-composite films was calculated to be 49 kj/mol ... -
