Faint emission lines in the spectrum of the Orion Nebula and the abundances of some of the rarer elements 来自 Semantic Scholar 喜欢 0 阅读量: 40 作者:DE Osterbrock,HD Tran,S Veilleux 摘要: Measurements of the emission lines, down to a faint level, in one bright region near the Trapezium...
The X-ray emission spectrum was analyzed and the results showed that comet C/1999 S4 (LINEAR) from the Oort cloud region (long-period) and comet 9p/Tempel 1 from the Kuiper Belt region (short-period) had the highest abundances of the different elements. The ds9...
The prism causes the different wavelengths of light to be separated. By looking at which wavelengths of light are seen, it is possible to determine what elements created the emission spectrum.Atomic Line Emission Spectrum Different types of spectrum can be produced. If white light is put through...
These instruments include both the iFR analysis mode, which measures the entire wavelength range in one measurement, and a eUV analysis mode, which measures the UV region of the spectrum with greater sensitivity. Learn more Semi-quantita...

Absorption Spectrum is the fraction of incident radiation absorbed by the material over a range of frequencies. This spectrum is mainly used to determine the atomic and molecular composition of the material. To know more, visit BYJU’S - The Learning App
The shape of the near-infrared thermal emission spectrum is mostly determined by the manner in which lava is erupted; a lava fountain has a high colour temperature (which is itself an approximation of a complex surface temperature–area distribution), whereas a lava flow of the same composition...
Absorption and emission of pristine-like semiconducting monolayers of BN, AlN, GaN, and InN are systematically studied by ab-initio methods. We calculate the absorption spectra for in-plane and out-of-plane light polarization including quasiparticle and excitonic effects. Chemical trends with the cati...

A very unique property of organic materials is that, due to their broad photoluminescence (PL) spectrum, a laser wavelength produced from them can be turned over a wide range [3]. Among the various types of organic materials, those that are soluble have the advantage of easy processability. ...
