Title: Composition-dependent surface chemistry of colloidal Ba_xSr_1-xTiO ₃ perovskite nanocrystals

Abstract

Ba_xSr_1-xTiO₃ perovskite nanocrystals, prepared by the vapor diffusion sol-gel method and characterized by state of the art surface techniques, display significantly different O-H stretching frequencies and adsorption properties towards CO₂ as a function of the alkaline earth composition (Ba vs. Sr). Lastly, the difference of properties can be associated with the more basic nature of BaO-rich than SrO-rich surfaces.

Local Structure of Ba_1-xSr_xTiO₃ and BaTi_1-yZr_yO₃ Nanocrystals Probed by X-ray Absorption and X-ray Total Scattering

Journal Article Rabuffetti, Federico A. ; Brutchey, Richard L. - ACS Nano

The effect of isovalent chemical substitution on the magnitude and coherence length of local ferroelectric distortions present in sub-20 nm Ba_1–xSr_xTiO₃ (x = 0.0, 0.30, 0.50, 1.0) and BaTi_1–yZr_yO₃ (y = 0.0, 0.15, 0.50, 1.0) nanocrystals synthesized at room temperature is investigated using X-ray absorption near edge structure (XANES) and pair distribution function analysis of X-ray total scattering data (PDF). Although the average crystal structure of the nanocrystals is adequately described by a centrosymmetric, cubic Pm3¯m space group, local ferroelectric distortions due to the displacement of the titanium atom from the center of the perovskite lattice are observed for allmore »« less

Low-temperature synthesis of homogeneous solid solutions of scheelite-structured Ca_1-xSr_xWO₄ and Sr_1-xBa_xWO₄ nanocrystals

Journal Article Culver, Sean P. ; Greaney, Matthew J. ; Tinoco, Antonio ; ... - Dalton Transactions

Here, a series of compositionally complex scheelite-structured nanocrystals of the formula A_1-xA’_xWO₄ (A = Ca, Sr, Ba) have been prepared under benign synthesis conditions using the vapor diffusion sol–gel method. Discrete nanocrystals with sub-20 nm mean diameters were obtained after kinetically controlled hydro- lysis and polycondensation at room temperature, followed by composition-dependent thermal aging at or below 60 °C. Rietveld analysis of X-ray diffraction data and Raman spectroscopy verified the synthesis of continuous and phase-pure nanocrystal solid solutions across the entire composition space for A_1-xA’_xWO₄, where 0 ≤ x ≤ 1.

The Surface Chemistry and Structure of Colloidal Lead Halide Perovskite Nanocrystals

Journal Article Smock, Sara R. ; Chen, Yunhua ; Rossini, Aaron J. ; ... - Accounts of Chemical Research

Since the initial discovery of colloidal lead halide perovskite nanocrystals, there has been significant interest placed on these semiconductors because of their remarkable optoelectronic properties, including very high photoluminescence quantum yields, narrow size- and composition-tunable emission over a wide color gamut, defect tolerance, and suppressed blinking. These material attributes have made them attractive components for next-generation solar cells, light emitting diodes, low-threshold lasers, single photon emitters, and X-ray scintillators. While a great deal of research has gone into the various applications of colloidal lead halide perovskite nanocrystals, comparatively little work has focused on the fundamental surface chemistry of these materials.more »« less

Magnetic and dielectric property control in the multivalent nanoscale perovskite Eu_0.5Ba_0.5TiO₃

Journal Article Farahmand, Nasim ; McGinn, Christine K. ; Zhang, Qize ; ... - Nanoscale

We report nanoscale Eu_0.5Ba_0.5TiO₃, a multiferroic in the bulk and candidate in the search to quantify the electric dipole moment of the electron. Eu_0.5Ba_0.5TiO₃, in the form of nanoparticles and other nanostructures is interesting for nanocomposite integration, biomedical imaging and fundamental research, based upon the prospect of polarizability, f-orbital magnetism and tunable optical/radio luminescence. We developed a [non-hydrolytic]sol–[H₂O-activated]gel route, derived from in-house metallic Ba_(s)/Eu_(s) alkoxide precursors and Ti{(OCH(CH₃)₂}₄. Two distinct nanoscale compounds of Ba:Ti:Eu with the parent perovskite crystal structure were produced, with variable dielectric, magnetic and optical properties, based on altering the oxidizing/reducing conditions.

Effect of oxygen gas and annealing treatment for magnetically enhanced reactive ion etched (Ba{sub 0.65},Sr{sub 0.35})TiO{sub 3} thin films

Journal Article Baishun, Zhang ; Zuci, Quan ; Tianjin, Zhang ; ... - Journal of Applied Physics

Sol-gel-derived (Ba{sub 0.65},Sr{sub 0.35})TiO{sub 3} (BST) thin films were etched in CF{sub 4}/Ar and CF{sub 4}/Ar/O{sub 2} plasmas using magnetically enhanced reactive ion etching technology. Experimental results show that adding appropriate O{sub 2} to CF{sub 4}/Ar can better the etching effects of BST films for the increase of etching rate and decrease of etched residues. The maximum etching rate is 8.47 nm/min when CF{sub 4}/Ar/O{sub 2} gas-mixing ratio is equal to 9/36/5. X-ray photoelectron spectroscopy (XPS) data confirm accumulation of reaction products on the etched surface due to low volatility of reaction products such as Ba and Sr fluorides, andmore »« less
