Transitions using Fluorescence Spectroscopy

  1. Mar 20, 2012 #1
    Hi all!

    I'm doing undergrad research work using fluorescence spectroscopy on crystals. My adviser believes that we should be able to find new transitions via this method, but I'm rather unsure about how steady mental ground my adviser is sitting on, as he is very old.

    Right now I am thinking that I might be able to use DFT to find the electronic energy gaps and match them with my emission peaks, but doing this on a crystal will require a lot of training I don't have and a lot of time to set up and run the calculations.

    Additionally, a previous doctoral candidate used the Extended Huckel method to identify energy gaps. I don't know much about this method, but I am in the process of looking for some literature on it.

    I am hoping that I might be able to find someone out there with more experience than myself with solid state fluorescence. Any books and journal articles that might be helpful would be great as well.

    I have already done a thorough reading of "Principles of Fluorescence Spectroscopy" by Lakowicz and "Excited State Lifetime Measurements" by Demas. Both have been very helpful with the individual instruments, but forming them together into something coherent has been a challenge.

    I have a PTI spectrofluorometer and a homemade instrument for measuring lifetimes at my disposal. Both can be cooled to liquid nitrogen temps and held anywhere between. I also have a node on the supercomputer on my campus.

    Thanks!
