TEM micrographs of colloidal gold particles produced by different X-ray exposure times: (a) 30 s; (b) 1 min; (c) 5 min and (d) 15 min for 10 ml precursor solution ([HAuCl4] = 1 mM). These results reveal a complex series of phenomena as discussed in the text, and in particular the size changes as a function of exposure.
