The effect of pH on particle agglomeration and optical properties of nanoparticle suspensions

The results show that pH may have significant effect on the optical properties involving NPSs. Adjusting the pH value based on the isoelectric point of the nanoparticle is an efficient method when specific radiative properties are required for specific applications. Different regimes of the dependent/independent scattering can be obtained by changing the pH of a particular nanoparticle suspension.
