In this work we present a simple method to obtain silver sols stabilized by tetrazole derivatives. The well established metal precursor silver nitrate and the reductant sodium borohydride have been combined with 5-R-tetrazoles (R = CH(3), NH(2)) acting as stabilizing ligands. Depending on the utilized tetrazole, different agglomeration kinetics could be observed. Long term stability and agglomeration processes have been in situ investigated by the use of UV/Vis- and Raman-spectroscopy.
