The emission spectrum of protactinium in the 0·8–3·0 μ region

Spectrochimica Acta, 1963
The emission spectrum of Pa/sup 231/ from an electrodeless discharge tube was observed in the region of 0.8 to 3.0 mu . Wavelengths and intensities were measured for about 1200 lines, many of which show hyperfine structure. (auth)

Excitonic emission of BGaN grown on (0 0 0 1) 6H–SiC by metal-organic vapor-phase epitaxy

Journal of Luminescence, 2000
Abstract 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.

Emission bands of AIH (X1Σ+): The 2-0 sequence

Journal of Molecular Spectroscopy, 1987
Abstract 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

The role of adsorbates in the Na+-induced kinetic emission of electrons from Ru(0 0 0 1)

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
Abstract Electron emission was measured from clean and adsorbate-covered Ru(0 0 0 1) surfaces under bombardment by 120–1620 eV Na + ions. A kinetic process is solely responsible for the emission of electrons in these systems, as the low ionization energy of Na excludes any potential emission.

Enhancement in emission angle of the blue LED chip fabricated on lens patterned sapphire (0 0 0 1)

Solid-State Electronics, 2010
Abstract 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 ...

Absorption and emission spectrum of bis-(triphenylphosphine)-dicarbonylnickel(0)

Inorganic Chemistry Communications, 2000
Abstract 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.

New detected CO(1-0) emission from planetary nebulae

Science in China Series A: Mathematics, 2000
We report the results of CO(1-0) (J=l-0) observations for 20 selected planetary nebulae (PNe), using the 13.7 m radio telescope of Purple Mountain Observatory at the Qinghai Station. Due to weak CO(1-0) emission, long integrated time observations have been carried out for most of sampled PNe.

Ion-bombardment induced light emission from Si(1 0 0) surfaces under continuous germane exposures

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005
Abstract The intensities of the optical spectral lines emitted from a Si(1 0 0) surface under Ar + ion bombardment are studied as a function of the ion kinetic energy (1–5 keV) and the partial pressure of germane. In these experiments, the ion flux is held constant while either the bombardment energy or the partial pressure of germane is varied. The

Molecular emission of 13CO (J=1−0) and C18O (J=1−0) from OMC-3

Chinese Astronomy and Astrophysics, 2001
Abstract 13CO (J = 1 − 0) and C18O (J = 1 − 0) emissions of the OMC-3 in the Orion A molecular cloud were mapped with the 13.7 m millimeter wave telescope of Purple Mountain Observatory using a higher spatial resolution. The overall structure of the cloud and the average physical parameters of all the 13CO (J = 1 − 0) and C18O (J = 1 − 0) cores are ...
