Hi!

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.
