16.Like the visible spectrum,an atomic emission spectrum is a continuousrange of colors.17.Each element has a unique atomic emission spectrum.18.A flame test can be used to identify the presence of certain elements ina compound.19.The fact that only certain colors appear in an element’s at...
Contrary to wavelengths lower than 7 μm and greater than about 23 μm, emission spectrum in this wavelength range does not look like a black body due to absorption or emission by water vapour, carbon dioxide and ozone. In wet atmospheric conditions, the background emission is increased. The...
Emission Spectra In subject area: Chemistry An optical frequency comb (OFC) is a mode-locked laser with a comb-like emission spectrum, that is, equally spaced, discrete frequency lines spread over the wide spectrum bandwidth. From: Molecular and Laser Spectroscopy, 2020 About this pageAdd to Me...

The negatively charged nitrogen-vacancy center (NV) presents remarkable spin-dependent optical properties that make it an interesting tool for magnetic field sensing. In this paper we exploit the polarization properties of the NV center absorption and emission processes to improve the magnetic sensitivity...

We first address the THz-emission signal from a NiO\((001)\)(10 nm)/Pt(2 nm) bilayer (see Methods and refs. 26,27) when excited by 100 fs near-infrared (NIR) pulses under normal incidence (see Fig. 1a). The magnetic configuration of NiO is detailed in Supplementary Note ...
radiation emissioncollapse modelsperturbation theoryWe compute the spectrum of radiation emitted by a generic quantum system interacting with an external classic noise. Our motivation is a wish to understand this phenomenon within the framework of collapse models. However, the computation is general and ...
Excitation by narrow-band lasers may result in the selective population of wanted levels, which emit their excitation energy as fluorescence photons. Such a laser-induced fluorescence (LIF) spectrum is much simpler than the emission spectrum of a gas discharge, where the superposition of fluorescence...
In the ET-based PEC sensors, overlap between the emission spectrum of quantum dots (QDs) and the absorption spectrum of noble metal nanoparticles (NPs) causes excitation of the plasmon resonance of the NPs, resulting in the generation of intense local electric fields around the NPs. It perturb...
