“…[3][4][5][6][7] Other methods to deposit/synthesize doped ZnS films and nanocrystals include: the aqueous method, 6 chemical bath deposition, 7,8 refluxing technique, 9 precipitation method, 10,11 pulsed laser ablation, 12 solid state reaction method, 13 solvothermal technique 14 and hydrothermal method, 15,16 aerosol assisted chemical vapour deposition and colloidal thermolysis. [17][18][19][20][21][22][23][24] Among these, CBD is the simplest and most cost effective method to synthesize thin films and nanocrystals. The only report found on cobalt doping in ZnS via CBD was presented by Tang et al 7 showing the enhancement in efficient ultraviolet emission of ZnS nanospheres after cobalt doping.…”
