YAG (Y3Al5O12) opticaly stimulated luminescence

  1. Feb 14, 2013 #1

    Can anyone help me with information about pure YAG luminescence spectra
    (ideal case will be excitation with continuous laser source at 367 nm [Nitrogen] )
    or even energy levels diagram?

    Thanks in advance

    As far as I know pure YAG crystal is transparent at this wavelength. What is the reason for the luminescence do you mean?

    Well. I haven't found any references on this theme. It's the main reason why I ask this question.
    The main topic of my research is YAG ceramics (undoped). And it GLOWS with green light
    when I use nitrogen laser as excitation source.

    And does an ordinary crystal YAG glow? May be there are some admixtures?

    Ammonium bicarbonate was used as a precipitator. There is possibility of presence of small portion in sample.
