CVD of AgI Complexes with Tertiary Phosphines and Perfluorinated Carboxylates—A New Class of Silver Precursors

Abstract

COOAg (2) have been used as precursors for the CVD of silver layers in the temperature range 493±623 K. The thin films obtained were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), scanning tunneling electrochemical microscopy (STEM), X-ray photoelectron spectroscopy (XPS), and temperature variable infrared (IR) measurements. The SEM images of Ag films grown from 2 exhibited a surface with a grain size in the range 0.4±1.5 lm, whereas from 1 the size was~0.1 lm. This was confirmed by the STEM studies. The better stability of 1 in the vapor phase was proved by temperature variable IR spectra (373±523 K). Mass spectrometry (MS) images confirmed the presence of the monomeric and dimeric species, and the recombination ions transported in vapors. The XPS image analysis of the silver layers revealed the presence of some carbon impurities. The films demonstrated good adhesion to silicon substrates.

Green synthesis of silver/montmorillonite/chitosan bionanocomposites using the UV irradiation method and evaluation of antibacterial activity

“…[1][2][3] Many methods can be used for synthesis of metal nanoparticles, including photoreduction or chemical reduction in aqueous medium with various polymer surfactants, 4,5 chemical reduction in soft matrices (eg, reverse micelles) 6 or in solid matrices (eg, mesoporous silicate), 7 and chemical vapor deposition. 8 Applications have been found for silver nanoparticles (Ag-NPs) in the high-sensitivity fields of biomolecular detection and diagnostics, 9 antimicrobials and therapeutics, submit your manuscript | www.dovepress.com…”

Time-dependent effect in green synthesis of silver nanoparticles

“…7 There are many methods for synthesizing metal nanoparticles, including photo reduction, 8 laser ablation, 9 chemical reduction in aqueous media with different polymer surfactants, 10,11 reduction of chemicals in soft matrices, [12][13][14] reduction of chemicals in solid matrices (eg, mesoporous silicate), 15 and chemical vapor deposition. 16 Silver nanoparticles (Ag-NPs) are widely used as catalysts, [17][18][19] photo-catalysts, [20][21][22] and in surface-enhanced Raman spectroscopy [24][25][26] as well as chemical analysis. …”

Synthesis and Structure of Compound Bis-benzylamino-silver(I) Benzylcarbamate

“…The carboxylate only acts as the charge balancer of the compound. This has great difference with other carboxylate-containing silver compounds, in which the carboxylate usually ligates to the silver atom [2,5,26,27]. For example, in the molecular structure of compound bis-triphenylphosphine-silver(I) stearate [((C 6 H 5 ) 3 P) 2 Ag(O 2 C(CH 2 ) 16 CH 3 )], the silver is four coordinate: the carboxylate symmetrically chelates the silver, while the triphenylphosphine ligands occupy the third and fourth coordination sites [7].…”

“…A number of them have been synthesized, characterized and applied, including perfluorinated carboxylate silver(I) [1], perfluorinated carboxylate trimethylphosphine silver(I) [2,3], (b-diketanato) silver(I) bis(trimethylsilyl)acetylene [4], silver(I) alkanoates [5,6], bis-triphenylphosphine-silver(I) stearate [7], silver(I) b-diketiminate complexes [8], crown ether silver(I) carboxylate complex [9], and so on.…”
