单词 emission spectrum
释义

Definition of emission spectrum in English:

emission spectrum

noun
  • A spectrum of the electromagnetic radiation emitted by a source.

    Compare with absorption spectrum
    Example sentencesExamples
    • The collection of wavelengths of light emitted by hydrogen gas is called the emission spectrum of hydrogen, and there is a corresponding spectrum for absorption.
    • In this way, the mean relative intensities of the emission spectra were calculated to obtain an averaged emission spectrum for each species.
    • Then, comparing the companion's infrared emission spectrum with spectra calculated from models of gas giants, they concluded that the companion is most likely two to three times as massive as Jupiter.
    • The emissions are then analyzed and separated into an emission spectrum that is characteristic for each element.
    • In liposomes the excitation spectrum is shifted to higher wavelengths and the emission spectrum to lower wavelengths, typical of a fluorophore moving into a more hydrophobic environment.
    • It is likely that both the absorption spectrum and the emission spectrum are changed at high intensities with respect to the low-intensity spectra of DsRed recorded by conventional spectrometers.
    • The position of the rose bengal emission spectrum in the trypsinbound state resembles the emission spectrum of rose bengal in neat acetone.
    • This external cavity configuration allows the wavelength of the laser to be tuned across the broad emission spectrum typical of glass-host lasers by changing the prism angle.
    • The gain or the stimulated emission spectrum should be spectrally similar to the steady-state fluorescence spectrum and show similar solvent dependence.
    • First, the emission spectrum of the donor molecule must overlap with the absorbance spectrum of the acceptor.
