In this equation, the exponential factor 𝑛 can be in the range of 1 to 4, and is equal to 1 in the case of ideal heterogeneous nucleation. By nonlinear curve fitting and minimization of least square residuals we were able to solve the Avrami parameters (A, K, and n). The results show that a more preferred heterogeneous nucleation behavior is evident in the case of HLNPs with a smaller particle size (HL85NP, d = 60 nm, n = 1.02), compared to the larger ones (HL85NP, d = 114 nm, n = 1.36). This supports our hypothesis that the particle size of cured HLNPs directly affects the formation of silver nanoparticles in the colloidal dispersion. It is thus possible to tune the surface coverage of the hybrid nanoparticles by using stabilized HLNPs of predetermined size as reducing agent.
