If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

My above description more sounds like "Fluorescence process" and I think WLS process can do the job, isn't it?
However, is WLS process decent for the process that involves one higher energy photon (which is still within optical photon range) causes excitation of multiple lower energy photons? e.g. Europium sulfate fluorescing red under ultraviolet light; I posted it in physics forum but no one answers my question yet. Hopefully I can find some help here. Thanks a lot in advanced.
