“…The slight absorption of the precursor/PMMA film at λ =355 nm seems to be sufficient to cause the photoconversion of the precursor to SnO 2 NPs in the film. As previously reported, due to the polymeric nature of the tin(II) precursor, acetate groups can be easily detached upon UV pulsed laser irradiation at λ =337 nm . Therefore, in the present case, irradiation at 355 nm could result in photocleavage of the precursor and subsequent creation of the initial [Sn−O] network essential for further growth of NPs .…”

The localized in situ formation of tin dioxide (SnO ) nanoparticles embedded in poly(methyl methacrylate) (PMMA) films is presented. This is achieved by the photoinduced conversion of the tin acetate precursor included in polymeric films, through controlled UV or visible pulsed laser irradiation at λ=355 and 532 nm, respectively. The evolution of the formation of nanoparticles is followed by UV/Vis spectroscopy and shows that their growth is affected in different ways by the laser pulses at the two applied wavelengths. This, in combination with electron microscopy analysis, reveals that, depending on the irradiation wavelength, the size of the nanoparticles in the final nanocomposites differs. This difference is attributed to distinct mechanistic pathways that lead to the synthesis of small nanoparticles (from 1.5 to 4.5 nm) at λ=355 nm, whereas bigger ones (from 5 to 16 nm) are formed at λ=532 nm. At the same time, structural studies with both X-ray and electron diffraction measurements demonstrate the crystallinity of SnO nanoparticles in both cases, whereas XPS analysis confirms the light-induced oxidation of tin acetate into SnO . Taken all together, it is demonstrated that the pulsed laser irradiation at λ=355 and 532 nm leads to the formation of SnO nanoparticles with defined features highly dispersed in PMMA solid matrices.

“…While spectroscopic investigations of many of these complexes has been comprehensive, structural characterization was complicated due to their polymeric nature. 25,30 We set out to understand how structure and bonding in the solid state and gas phase affects the thermochemical properties of tin trifluoroacetates, and thus evaluate their suitablity as vapor-phase precursors for FTO.…”

<div> <div> <div> <p>Simple tin carboxylates make up a family of important industrial catalysts and precursors for deposition of SnO2 thin films. However, their structures remain disparately characterized, and tin trifluoroacetates have been particularly elusive. Here we report on a combined X-ray diffraction (XRD), gas phase electron diffraction (GED) and density functional theory (DFT) study into the structure and bonding of tin(II) and tin(IV) trifluoroacetates to understand their influence on thermal stability and volatility. Tin(II) bis(trifluoroacetate) (1′) eliminates trifluoroacetic anhydride upon sublimation to form the linear polymeric hexatin(II)-di-μ -oxy-octakis-μ-trifluoroacetate (1F ), which itself sublimes (1 Torr at 191 C) as a 1:1 mixture of 1 and ditin(II)-μ-oxy-bis-μ-trifluoroacetate (1′′). Tin(IV) tetrakis(trifluoroacetate) (2F) is also polymeric in the solid state, but evaporates as a monomer at low temperatures (1 Torr at 84 ◦C). Together they make a family of multifunctional Lewis acidic and basic building blocks for supramolecular organization of clusters and polymers in the solid state. Anomalous trends in the volatility of these trifluoroacetates and their hydrogenated derivatives can be rationalized by consideration of their modes of polymerization with respect to the thermodynamics of evaporation. Both 1F and 2F combine high thermal stability and volatility, and are demonstrated to be complementary, safe, and green potential precursors for chemical vapor deposition (CVD) or atomic layer deposition (ALD) of earth-abundant transparent conducting F-doped SnO2. </p> <div><div><div> <p> </p> </div> </div> </div> </div> </div> </div>

In this article is a report of SnO2 deposition by aerosol‐assisted (AA)CVD from tin complexes, [Sn(18‐Cr‐6)Cl4] and [Sn(H2O)2Cl4](18‐Cr‐6). The structure and properties of the precursors, used to synthesize SnO2 layers by AACVD for the first time, are characterized with the help of X‐ray diffraction (XRD), infrared (IR), and thermogravimetric analysis (TGA). Each complex is deposited by AACVD at 250, 400, and 500 °C in a flow of N2. The resulting films are studied by XRD and atomic force microscopy (AFM). Gas‐sensing properties of the deposited layers are tested to 10 ppm NO2 in air. The maximum sensor response to the analyte is measured at 300 °C.
