Abstract

The habit of {110} AgCl crystals changes by incorporation of Br^- or I^- ions during crystal growth. At high Br content the {110} habit of AgCl turns into an irregular {100} habit in the presence of the growth modifying agent. The incorporation of a rather low amount of I^- ions causes the {110} habit of AgCl to disappear and to be modified into a {100} habit. Adsorption of 3,3’-diethyl-9-methyl thiocarbocyanine on the crystals follows very well the aggregation rule found previously.
