Can we measure the band energy gap from Fluorescence spectra

    Can we measure the band energy gap from Fluorescence spectra?
    If yes, in what way? the excitation spectra or the emission spectra or both

    Is there a good reference on this subject specifically
    :smile:

    thanks but in what way? the excitation spectra or the emission spectra or both
    i'm using emission spectra and i calculate the Eg from wavelength of maximum intensity
    does my way correct

    and i found the Eg from urbach edge is begger than the Eg from Fluorescence(emission spectra) and i conclude that there is defect in my samples
    does my way correct?????????

    i need reference for beginner or intermediate

    You appear to have conducted an actual experiment which has provided results you did not expect.
    I don't think anyone can help with that without knowing the details of the experiment itself. Write up what you have so far, formally, and maybe someone will read it over.

    I gave you an example where this was done -- did you read it?
