Can anyone suggest the best method to calculate the europium luminescence spectra theoretically ?

I am studying the complexation of Eu(III) with aminoacids like picolinates in aqueous solutions by luminescence spectroscopy. I found experimentally the variations in intensity of the transitions...

For nanoparticle detection, which pulsed (micro, nano, pico and femto second) laser is most appropriate and why ?

Basically I would like to know the effect of pulse duration of a laser on the plasma formation. I studied the formation of thorium colloids by a diode pumped solid state laser Nd:YAG with 10 ns...

Is it possible to resolve the metal and ligand absorption in the complexation studies, when both metal and ligand have absorption in the UV region ?

I am studying the Europium complexation with a carboxylate ligand. Europium has strong absorption in the UV region, my ligand also has the same, almost overlapping. The Europium addition and NaOH...
