N2 - According to the principles of simultaneous equilibria and mass equilibria, CuInSe2(CIS) were prepared by total aqueous process at normal pressure and room temperature. A series of thermodynamic equilibrium equations were deduced for the complex system of Cu+-In3+-Se2--NH3-L2--Cl--H2O (T=298 K), and the equilibrium curves of lgc-pH were drawn. It was found from these equilibrium diagrams that [NH3]T primarily affected the [Cu+]T concentration, [L2-]T influenced the [In3+]Tconcentration, and [Cl-]T had impact on both. The highest precipitation coefficient was obtained at pH 7.0-8.5. As a result, based on the principles of simultaneous equilibria and mass equilibria of the Cu+-In3+-Se2--NH3-L2--Cl--H2O system (T=298 K) and used total aqueous process at normal pressure and room temperature, CIS nanoparticles can be synthesized by adjusting the pH value to 7.0-8.5, and their size is about 20 to 50 nm.
