We are working on Gold Nano particles and their peak absorbance is 1.8 unit for 570 nm.
we want to extend this analysis towards spectrum band width and kinetics,
please suggest some suitable method and related research articles.
You have found out the wavelength of maximum absorption or SPR as 570 nm. Use dilute gold sol such that you get absorbance in the range of 0.5 to 1. You can follow the kinetics by testing the gold sol for absorbanceat regular interval of time till you get highest absorbance value and continue thereafter too. As according to Beer-Lambert's law absorbance is directly proportional to concentration. You can check the stability of gold sol during the process. However, kinetics can be followed only after identifying SPR and calibration curve development. You can determine the wavelength of maximum absorption and thereby band width.

I think a new compound has formed and therefore do an x-ray phase analysis
Use different concentrations since absorbance is directly proportional to concentration.
