What is the significance of peak at 288 eV in the XPS 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...

Is there any possibility of increase in flourescence intensity as concentration increases (in quantum dots)? Aggregation has any effect on intensity?

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.
