What is the magic number in eV for electrons in glass, transparent...

  1. May 17, 2016 #1
    - liquids, and plastics for light to transmission completely through the material.
    Is this eV level known in glass, liquid, and transparent plastics, for electrons to transmission light.

    Physicists say that "In most solid or liquid substances, the electron structure is so complex that emissions are not confined to one wavelength, but are smeared out.
    Therefore, emission features of solids and liquids are barely discernible."
    So basically its like its physicists are saying its to hard to try, because the material maybe has so many different elements, so you cannot find the absorption band of a certain color of light.
    But what about a material composed of one atomic element, not mixed with any others.
    Could it then be possible to find the absorption, and emission spectrum of the solid material.
    I am grateful for your help, anything helps, even a few words. :D

    There is no magic number.
    Usually there are no separate absorption bands, even if the material just has one single element. The absorption bands often overlap.

    You can always find an absorption and emission spectrum, but it won't have the nice lines you can see in gases.
