3-Mercaptopropionic, 4-mercaptobenzoic, and oleic acid-capped CdSe quantum dots : interparticle distance, anchoring groups, and surface passivation
(2019) [Artigo de periódico]The optoelectronic properties of quantum dots are strongly controlled by the chemical nature of their surface-passivating ligands. In this work, we present the synthesis, characterization, and surface modification of CdSe ... -
Eucalyptus oil-mediated synthesis of gold nanoparticles
(2018) [Artigo de periódico]The search for efficient methods for the synthesis of metal nanoparticles has been widely explored. Within this context, the use of biological materials such as plants, algae, bacteria and fungi has been reported to various ... -
Interface dependent plasmon induced enhancement in dye-sensitized solar cells using gold nanoparticles
(2015) [Artigo de periódico]We report a study on plasmon-induced photoelectrochemistry from gold nanoparticles incorporated in dye-sensitized solar cells, assembled in two different configurations: TiO2/Aunanop/Dye and TiO2/Dye/Aunanop. Although the ... -
Peering into the formation of template-free hierarchical flowerlike nanostructures of SrTiO3
(2020) [Artigo de periódico]The development of efficient advanced functional materials is highly dependent on properties such as morphology, crystallinity, and surface functionality. In this work, hierarchical flowerlike nanostructures of SrTiO3 have ... -
Polypyrrole/ionic liquid/Au nanoparticle counter-electrodes for dye-sensitized solar cells : improving charge-transfer resistance at the CE/electrolyte interface
(2019) [Artigo de periódico]To provide a viable alternative for counter electrodes used in dye sensitized solar cells, polypyrrole (PPy) based films have been synthesized via electrochemical deposition in the presence of the ionic liquid 1-butyl-3- ... -
