Correct spelling for the English word "linneon" is [lˈɪnɪən], [lˈɪnɪən], [l_ˈɪ_n_ɪ__ə_n] (IPA phonetic alphabet).
I apologize, but "linneon" does not have a dictionary definition as it is not a recognized word in the English language. It is possible that you may have misspelled the term or it could be a term specific to a certain field or context not commonly used or known.
