Help required with chemical formula and spectrophotometry

  1. Mar 9, 2013 #1
    Hi guys,

    I have what I hope is a simple question. basically I have a known crystal structure with a known dopant, however I don't know what the charge on the dopant is and I can't find it in any papers. Now I'm not sure if this is something I just need to find or whether this is something I can determine from analysis (I did study chmistry to the highest secondary level but I can't actually remember much of the methodology). Anyway I would appreciate if someone could tell me the charges and explain how they were oobtained for the equation below (if possible):

    Lu2SiO5:Ce where Ce is the dopant

    Additionally, this material is a scintillator and I have measure the transmission for the 200-1000nm range. In the UV region there are a couple of transmission spikes that I would not expect for a scintillator. Could this be due to the Ce dopant?

    Thanks in advance.

    Jamie

    Thanks for that DrDu. for some reason I never thought to actually search for the formula and instead used the common name LYSO. Just goes to show how easily you can overlook the obvious.
