Abstract

The gold density enters some indirect determination of gold properties as an input parameter. Reported gold density of 19 320 kg m<sup>–3</sup> at standard conditions is correct for gold bulk or macro-sized specimens. For nano-sized specimens (nano-clusters, nano-layers), however, this standard density value need not be applicable. This work deals with gold density as a function of the nano-structure size. The calculated density was compared with experimental one performed for gold sputtered onto glass or poly(ethylene terephthalate) substrates. Calculated gold density was found to increase from 11 249 to 19 304 kg m<sup>–3</sup> when the characteristic dimension of gold nano-structures increases from 0.7 to 82 nm. At the same time the free volume fraction in nano-structures decreases from 57 to 26%.
