I recorded the emission spectra of a compound in different solvents upon excitation at 500 nm. I observed emission peak at about 725 nm in water, thf and methanol with high emission intenisty. Is it emission peak or something else? What could be the reason for these emission maxima in NIR region only in three solvents (water, THF and methanol).
attached file is the graph of recorded spectra in diff solvents.
