I have prepared Mn4+ doped inorganic compound in which I have observed Mn4+ characteristic excitation and emission band. The emission of Mn4+ is observed at 682 nm under 365 nm emission. I want to make Tanabe-Sugano energy level diagram for this Mn4+ doped compound. Kindly provide the basic idea to draw T-S energy level diagram.
I am attaching the photo luminescent excitation and emission spectra of Mn4+ doped inorganic compound.
