Add a definition The above picture shows the visible lightemissionspectrumfor hydrogen. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Its fluorescenceemissionspectrumis very sensitive to solvent polarity, so pyrene has been used as a probe to determine solvent environments. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, there are dozens of laser dyes that can be used to span continuously theemissionspectrumfrom the near ultraviolet to the near infrared. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Light is collected using optical filters that match theemissionspectrumof the fluorophore. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This leads to an alteredemissionspectrum, which is significantly narrowed. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The lower section shows that theemissionspectrumof the donor dye must (partially) overlap with the absorption spectrum of the acceptor dye. From theCambridge English Corpus The resulting spectrum is able to match theemissionspectrumof a protoplanetary nebula. From theCambridge English Corpus Thus, there exists a good match between the flashboardemissionspectrumand the absorption proper ties of argon. From theCambridge English Corpus Theemissionspectrumis much broader in the present case than in the low light intensities. From theCambridge English Corpus Emitted light from this plasma amounts to an elementalemissionspectrumthat is collected and used to identify the composition of the target material1. From theCambridge English Corpus Theemissionspectrumcharacteristics of some elements are plainly visible to the naked eye when these elements are heated. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These definite characteristics allow elements to be identified by their atomicemissionspectrum. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Due to its high sensitivity to the mobility and presence of solvent dipoles, changes in theemissionspectrumcan be calculated from the generalized polarization. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. An example is theemissionspectrumof nebulae. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The collection would be equivalent to an array of semiconductors individually size tuned for optimal absorption at their bandgaps throughout the solar energyemissionspectrum. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It glows blue with anemissionspectrumpeak wavelength at 430 nm, which makes it useful as a wavelength shifter. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The principle of the atomicemissionspectrumexplains the varied colors in neon signs, as well as chemical flame test results (described below). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Starlight can be understood to be composed of three main spectra types, "continuous spectrum", "emissionspectrum", and "absorption spectrum". From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This collection of different transitions, leading to different radiated wavelengths, make up anemissionspectrum. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The fact that only certain colors appear in an element's atomicemissionspectrummeans that only certain frequencies of light are emitted.
