“…Although the nanocasting method is well-established for bulk samples (i.e., monoliths or powders), it has been less developed for MTF. 21,22,25 In this context, the use of mesoporous chalcogenide thin films (i.e., ZnS, CdS, ZnSe, CIGS, etc.) for photovoltaic applications represent an interesting approach for the design of inorganic− organic hybrid solar cells.…”

“…This limit of volume filling is similar to those found in nanoparticle-laden mesoporous systems, and might be due to partial blocking of the necks and pore clogging of the MSF as the number of infiltrations increases. 25 Oscillations at angles higher than θ c are due to the constructive interference of reflected X-rays on thin film interfaces and are known as XRR Kiessig fringes. 30,40,44 In the higher angle region (θ > 4θ c ) these periodic oscillations are related to the film thickness, d, according to…”

Mesoporous ZnS Thin Films Prepared by a Nanocasting Route

Mesoporous metal chalcogenides (e.g., ZnS, CuS, and derived mixed sulfide or selenides) show an extremely high potential in technological areas like catalysis, sensors, environmental protection, and photovoltaics. Although chemical bath deposition methods allow obtaining stable and porous metal chalcogenide films under mild and simple conditions, the reproducible preparation of highly ordered mesoporous sulfide thin films has been challenging so far. Herein, we present a simple and efficient synthetic method to prepare ZnS mesoporous thin films using a combination of a nanocasting approach and a successive ionic layer adsorption and reaction (SILAR) process for the infiltration. A mesoporous silica thin film, prepared by evaporation induced self-assembly (EISA), serves as the hard exotemplate for the formation of the mesostructured zinc sulfide. After selective etching of the silica framework, a stable and porous ZnS thin film is obtained, which replicates the pore structure of the hard template. A thorough combination of characterization techniques is used to assess the exotemplating process as well as the template removal.

“…The SnO 2 skeleton consist of nanocrystals of about 5 nm in diameter, in agreement with XRD and other works in the literature. 39 The fast Fourier transform (FFT) of selected regions in the image shows spots whose interplanar distance matches tetragonal SnO 2 . Selected area electron diffraction (SAED) analyses of the sample doped with higher Ni amount (9%) showed spots attributed to the NiO phase ( Fig.…”

“…More details on the modeling can be found in ref . It is worth mentioning that in the literature, a Bruggerman effective media approximation (B‐EMA) function is often used to model meso‐porous systems . However, in order to use this approach, the optical constants of the layer matrix must be known, and these are often obtained by studying non‐porous reference samples .…”

In this work the combination of ellipsometric porosimetry (EP) and electrochemical impedance spectroscopy (EIS) is extensively addressed in order to characterize the nanoporosity and further elucidate its influence on the water permeation properties of plasma enhanced-CVD SiO 2 layers. Pores with diameter in the range of 0.27-0.6 nm are studied by adopting a multisolvent/multi-ion approach, with EP and EIS, respectively. This combined study has brought to conclude that open pores larger than 0.42 nm are responsible for WVTR values in the range of 10 À3 -10 À5 gm À2 d À1 , while pores with diameter between 0.42-0.27 nm were found to drive the transition to excellent moisture barrier layers (10Moreover, it is shown that EIS is capable of detecting macro-scale defects, next to nanoporosity, being thus a powerful tool for the analysis of moisture barrier layers.
