Publikováno v: Thin Solid Films. 709:138190

Highly porous nanocrystalline TiO2 films were sensitized with ZnS semiconductor nanocrystals by using a three-step facile strategy. The TiO2 matrices were firstly impregnated with the zinc bis(benzyl)thiol precursor that, unlike many other metal chal

Publikováno v: Journal of Sol-Gel Science and Technology. 60:333-339

Polycrystalline, close-packed, homogeneous nanostructured ceria thin films were prepared by sol–gel process via dip-coating technique on soda-lime glass and (100)-oriented Si substrates. To produce the films, a sol was prepared using, as precursor,

Photocatalytic activity, hydrophilic and optical properties of nanocrystalline titania thin films prepared by sol-gel dip coating

Autor: Luciano Pilloni, A. Mevoli, Saverio Mazzarelli, Maria Cristina Ferrara, Leander Tapfer

Publikováno v: MRS Proceedings. 1352

Nanocrystalline anatase titania thin films were prepared by using two different precursor solutions, a highly acid solution (Sol-1) and a polymer-like solution (Sol-2), via the dip-coating technique on different substrates (-Si wafer, fused silica an

Journal of Physics D: Applied Physics, IOP Publishing, 2010, 43 (9), pp.95301. ⟨10.1088/0022-3727/43/9/095301⟩

Nanostructured titania thin films were prepared under controlled atmospheric conditions by the sol–gel dip-coating technique on glass, fused silica and (1 0 0)-silicon substrates. Two different sol–gel routes were employed by using different prec

Growth of CdS nanocrystals within mesoporous TiO2 films by using cadmium thiolates derivatives as unimolecular precursors

Autor: Vincenzo Resta, Anna Maria Laera, Leander Tapfer, Saverio Mazzarelli, Maria Cristina Ferrara, Anna Mevoli, Emanuela Piscopiello

Publikováno v: Scopus-Elsevier

In this work we report on the synthesis and the characterization of CdS nanocrystals (NCs) in mesoporous TiO2 anatase films as a first step towards the production of quantum dot sensitized TiO2 based solar cells. A novel in-situ approach has been dev

High mechanical-damage-resistant sol-gel coating for high-power lasers

Autor: M.R. Perrone, Saverio Mazzarelli, Jordi Sancho-Parramon, Maria Cristina Ferrara, Salvador Bosch, Maria Lucia Protopapa

Publikováno v: SPIE Proceedings.

This paper is a work-in progress report on the development of sol-gel coatings for high power laser systems in the near-UV, infrared region. Silica, titania and titania-silica acid catalysed sols were prepared by using tetraethoxysilane and titanium

Optical characterization of materials in sol-gel dip coatings

Autor: Salvador Bosch, Jordi Sancho-Parramon, Saverio Mazzarelli, Maria Cristina Ferrara

Publikováno v: SPIE Proceedings.

Optical properties of materials inside a multilayer stack may differ from those of single layers. This fact is specially noticeable in the case of sol-gel films obtained by dip coatings. We propose a method to determine the refractive index and thick
