In situ Fourier transform infrared (FTIR) absorption spectroscopy has been used to determine the fractional depletion of silane in a radio-frequency (ri) glow discharge. The technique used a simple single-pass arrangement and was implemented in a large-are ...
The stabilizing role of permanent Ir modifier deposited on W-treated (WTP) and Zr-treated (ZrTP) platforms of transversely heated graphite atomizer (THGA) was studied in detail by electrothermal at. absorption spectrometry (ETAAS) and different surface tec ...
Electrothermal at. absorption spectrometry is applied to study the release of the arsenic, antimony and bismuth atoms from pyrocoated graphite support. The influence of the chem. modifiers tungsten and palladium on the absorbance time profiles is exptl. ev ...
The absorbance signal in electrothermal at. absorption spectrometry is a result of the processes of atom formation and dissipation and 1st of all depends on the initial generation of atoms from the surface. The rising part of the absorbance time profiles c ...
We present a study of the effect of strong electron-phonon coupling on the levels of the D-5 term of Fe2+ in II-VI zinc-blende semiconductors. The nonperturbative approach leads to a dramatic decrease of the level spacings of the (5) Gamma(5) manifold of F ...
Electrothermal at. absorption spectrometry is applied to study the release of the selenium and tin atoms from pyrocoated graphite support. The Coats and Redfern and Sturgeon approaches were used for estn. of the apparent activation energies of atom release ...
A new spectral colour prediction model for a fluorescent ink printed on paper is presented. It is based on our previous work on transparent support 4 and on a new mathematical formalism which generalizes the Kubelka-Munk theory. The printed pape ...
The evolution of the argon metastable states density has been studied by absorption spectroscopy in power-modulated plasmas of argon and a mixture of 4% silane in argon. A small concentration of silane suppresses the argon metastable states density by mole ...
Advances in chem. modification electrothermal at. absorption spectrometry (ETAAS) are reviewed with an emphasis on the progress made after the publication of the previous extensive review (Tsalev et al., Spectrochim. Acta Rev. 1990, 13, 225). Among the top ...
Transmission spectra of ordered and disordered GaAs/Al0.3Ga0.7As superlattices (SL) were measured at 2 K. The experimental results are compared with numerical simulations obtained by means of a transfer matrix method. The numerical results indicate that a ...
