We demonstrate that spherical gold nanoparticles of relatively narrow size distribution (250 nm size, 40 nm standard deviation) and gold microclusters (composed by smaller nanoparticles of 30–100 nm in size) can be obtained from in situ nucleation of Au25− molecules in polyimide at temperatures fr ...
