Since acetylene is slightly acidic in nature, in basic medium can they aggregate? Because, as the pH of medium is increasing beyond 4, my material shows red shift in fluorescence spectrum.
While analysing the XPS spectrum of one newly synthesized carbon material, I have observed a peak at 288 eV which is deconvoluted into three peaks at 284.6 eV, 286 eV and 288 eV. I was expecting 2...

Fluorescence intensity is increasing as the time passes. Emission wavelength remains the same. Intensity is changing upon variation in concentration also. But, emission wavelength is still the same.
