Résumé : | It has been confirmed that the colour of hydrophobic gold hydrosols is not determined by particle size alone. For a given particle size, the absorption spectrum depends largely on the concentration of reagents used for the preparation of the sol. Relatievly stable blue hydrosols were obtained with concentrated reagents, by the nuclei method, whilst red or violet sols of the same dispersity were formed when dilute reagents were used.
