Figure 8
(a) TEM micrograph of colloidal gold particles formed in solutions with 2-propanol added, after a 5 min X-ray exposure; (b) visible-light absorption spectra of gold nanoparticles formed with different exposure times for a 10 ml precursor solution ([HAuCl4] = 1 mM). The amount of 2-propanol was 0.6 ml for each 40 ml of gold precursor solution.
