Electrochromic switching of electrodeposited ZnO+Zn5(OH) 8Cl2 films

Rayón Encinas, Emilio; Cembrero Cil, Jesús; Marí Soucase, Bernabé (Elsevier, 2011)

This study reports the effect of optical switching of electrodeposited ZnO + Zn5(OH)8Cl2 films on a gold electrode in a bath of 0.05 M Zn(NO3)2 + 0.1 M KCl. The coating turns black when cathodic polarization is applied yet ...
High-Efficiency Electrodeposition of Large Scale ZnO Nanorod Arrays for Thin Transparent Electrodes

Pullini, D.; Pruna, Alina Iuliana; Zanin, Stefano; Busquets Mataix, David Jerónimo (Electrochemical Society, 2012)

In the present work an effective technique to synthesize large-scale c-axis oriented ZnO nanorod (NR) arrays is presented. The manuscript reports a single-step cathodic electrodeposition, either in aqueous and organic ...
Influence of Deposition Potential on Structure of ZnO Nanowires Synthesized in Track-Etched Membranes

Pruna, Alina Iuliana; Pullini, Daniele; Busquets Mataix, David Jerónimo (Electrochemical Society, 2012)

Single-crystal ZnO nanowires long up to several microns were fabricated by one-step electrochemical deposition. A template-based process employing track-etched polycarbonate (TE-PC) membranes was used for this purpose. The ...
Nanostructured hybrid ZnO thin films for energy conversion

Moya Forero, Mónica Mercedes; ANURA SAMANTILLEKE; Mollar García, Miguel Alfonso; Marí Soucase, Bernabé (SpringerOpen, 2011)

We report on hybrid films based on ZnO/organic dye prepared by electrodeposition using tetrasulfonated copper phthalocyanines (TS-CuPc) and Eosin-Y (EoY). Both the morphology and porosity of hybrid ZnO films are highly ...
Photoluminescent properties of electrochemically synthetized ZnO nanotubes

Gracia Jimenez, J. M.; Cembrero Cil, Jesús; Mollar García, Miguel Alfonso; Marí Soucase, Bernabé (Elsevier, 2016-09)

ZnO nanotubes were prepared by a sequential combination of electrochemical deposition, chemical attack and regeneration. ZnO nanocolumns were initially electrodeposited on conductive substrates and then converted into ...
ZnO and CuO crystal precipitation in sintering Cu-doped Ni-Zn ferrites. II. Influence of sintering temperature and sintering time

Barba, Antonio; Clausell, Carolina; Nuño Fernández, Luis; Jarque, Juan Carlos (Elsevier, 2017)

[EN] This paper presents a study of the precipitation of ZnO and CuO crystals during the sintering of Cu-doped Ni-Zn ferrites. The nature of the resulting crystal precipitates were analysed using scanning electron microscopy ...
ZnO-based spinels grown by electrodeposition

Tortosa Jorques, María Dolores; Manjón Herrera, Francisco Javier; Mollar García, Miguel Alfonso; Marí Soucase, Bernabé (Elsevier, 2012-09)

We report on the synthesis of thin films of ZnCo 2O 4 and ZnMn 2O 4 spinels, as well as pure Co 3O 4 and Mn 3O 4 spinels, by means of electrodeposition. Spinel thin films have been analyzed by energy dispersive spectroscopy, ...
