Spectral analysis of the low energy Auger emission from a (0 0 0 1) ruthenium surface
Applied Surface Science, 2003Abstract The low energy Auger emission from a Ru(0 0 0 1) surface have been analysed by means of a cylindrical mirror analyser (CMA) within the range of the electron energy ( E ) from 27 to 37 eV as a function of the primary electron energy ( E p ), which was set from 170 to 450 eV in 20 eV steps. Three Auger transitions at following energies: 31.7,

b1Σ+ Emissions from group V–VII diatomic molecules. b 0+ → X1 0+, X2 1 emissions of AsI and SbI
Chemical Physics Letters, 1984Abstract Chemiluminescence from the b 0 + → X 1 0 + band system of AsI and of the b 0 + → X 1 0 + , X 2 1 systems of SbI in the near-infrared spectral region has been observed in a discharge flow system. Analysis of the spectra led to the spectroscopic constants (in cm −1 ) of AsI: ω e (X 1 , X 2 ) = 257 ± 2, ω e x e (X 1 , X 2 ) = 0.82 ± 0.2,

Absorption and emission spectrum of bis-(triphenylphosphine)-dicarbonylnickel(0)
Inorganic Chemistry Communications, 2000Abstract The complex Ni0(PPh3)2(CO)2 shows a red photoluminescence (λmax=650 nm) at r.t. It is suggested that this emission originates from a Ni0→PPh3 metal-to-ligand charge transfer triplet.

Emission bands of AIH (X1Σ+): The 2-0 sequence
Journal of Molecular Spectroscopy, 1987Abstract Seven bands of the 2-0 sequence of AlH in its X 1 Σ + ground state have been observed in emission from a carbon furnace and recorded with a Bomem interferometer. Improved values for the molecular constants have been obtained. The principal constants are B e = 6.3937(4), α 3 = 0.1868(3), 10 4 D e = 3.683(10), ω e = 1682.43, and

Absorption and Emission Spectrum of [Zn₄0(Acetate)₆]
1990The electronic spectrum of [Zn4O(acetate)6] in solution is characterized by an absorption (λmax.= 216 nm) and emission (λmax.= 372 nm) band; it is assigned to a ligand-to-metal charge-transfer (LMCT) transition, which corresponds to the band-gap transition of the semiconductor ZnO.

Enhancement in emission angle of the blue LED chip fabricated on lens patterned sapphire (0 0 0 1)
Solid-State Electronics, 2010Abstract Blue light-emitting diodes (LEDs) with an InGaN multi-quantum-well (MQW) structure were fabricated on a lens patterned sapphire substrate (LPSS) using a single growth process of metalorganic chemical vapor deposition (MOCVD). In the present study, the PSS with lens shape along the 〈0 0 0 1〉sapphire direction was fabricated by inductively ...

On the persistence of shocks to global CO2 emissions: a historical data perspective (0 to 2014)
Environmental Science and Pollution Research, 2022Anthropogenic emissions of carbon dioxide (CO2) are the most important greenhouse gas. However, until now, no research has investigated the persistence of global CO2 emissions over a very long period of time. This work aims to fill this gap by examining the persistence of shocks to global CO2 emissions with a dataset of more than 2000 years.

Otoacoustic Emissions and Tympanometry Screening Among 0–5 Year Olds
The Laryngoscope, 2002AbstractObjectives To determine the rate of otitis media (OM)‐associated transient evoked otoacoustic emissions (TEOAE) screening failure in a sample of preschool children, to evaluate concordance between TEOAE and tympanometry, to investigate risk factors for TEOAE failure, and to determine agreement between TEOAE failure and physician findings at ...

Excitonic emission of BGaN grown on (0 0 0 1) 6H–SiC by metal-organic vapor-phase epitaxy
Journal of Luminescence, 2000Abstract Reflection and photoluminescence spectra of boron gallium nitride (BGaN) layers were observed. BGaN layers were grown on (0 0 0 1) 6H–SiC substrates without any buffer layers by metal-organic vapor-phase epitaxy (MOVPE). The emission peaks that originated from free-exciton recombination were observed in these layers.

Quenching of emission and of photochemistry of pentacarbonyl(4-cyanopyridino)tungsten(0)
Journal of the American Chemical Society, 1980Abstract : The complex W(CO)5L,L = 4 cyanopyridine, is found to emit in room temperature methycyclohexane solution. The emission is centered around 630 nm and is 105 plus or minus 10 nsec in lifetime, gamma, at 25 C. Added 0.1 M ethanol does not change the charcteristics, and in this medium 1/gamma = 2.61x10 to the 8th power exp(-1960/RT).
