“…High Resolution Transmission Electron Microscopy (HR TEM) data show that the shape of the nanoparticles in real experiments on precursor-mediated nanoparticle growth in polymer films 26,31 is close to the spherical one. Thus, we assume that the relaxation of the shape of the nanoparticle toward the spherical shape is a fast process.…”

The inorganic nanoparticle growth within a polymer matrix is due to generation of the elementary species, the monomers, because of decomposition of the precursor compounds. The nucleation of the nanoparticles can be either homogeneous or heterogeneous. The model for heterogeneous nucleation and growth considered in this paper with some natural assumptions can explain experimentally observed exposure dependence of the UV-initiated CdS nanoparticle growth in poly(methyl methacrylate) (PMMA). The constraints on the values of the parameters imposed by the assumptions are discussed. Analytical solutions for the dynamics of the particle size distributions are obtained by reduction of the set of ordinary differential equations to the partial differential equation. The dependences of the particle size distributions on the parameters involved are found. This allows modeling the evolution of the optical absorption spectrum of the nanocomposite material due to nanoparticle growth.

A highly soluble Au(I) gold precursor is used to produce a nanocomposite material consisting of a polystyrene matrix and gold nanoparticles. Irradiation of such a material with nanosecond laser pulses at the plasmon resonance wavelength leads to the formation of highly luminescent black spots containing amorphous carbon, as confirmed by HR TEM analysis. A simple model, based on laser heating of a nanoparticle to a temperature of more than 2000 K and stabilization of this temperature by the endothermic process of polystyrene carbonization, fits well the dependence of the luminescent signal increment on the laser fluence.
