Is it an unknown? If you know the polymer, you have an idea where to look.
do you have a Uv-vis? It is very difficult to do fluorescence without a Uv-vis.
oncd you know the Uv-vis spectrum, you know to look for fluorescence at wavelengths just longer than the absorbance. And to excite at the lambda max for absorbance (or close to it)

Can you explain this point to me with your permission? I know the type of polymer, but I do not know the method, and I am still looking for more about it accurately. Can you help me with that Professor, thank you very much.
