“…[18][19][20] This latter method has attracted particular attention because of improvements in reactiont imes, purity,a nd reproducibility. [19] All of the methods employ ar ange of Group 11 metal sources, for example, AgNO 3 , [5,14] Ag(dedc) (dedc = diethyldithiocarbamate), [3,17] Ag 2 S, [9] CuCl, [15,21] and CuNO 3 ; [11] and Group 13 metal sources, fore xample, InCl 3 , [5,14] [In(dedc) 3 ] (dedc = diethyldithiocarbamate), [3,17] In(NO 3 ) 3 , [3,11] GaCl 3 , [21,22] and Ga 2 S 3.…”
