“…At its melting temperature of 60 1C, its vapor pressure (1.6 Â 10 À 1 Pa) is low enough [22]; thus, it is easier to handle than As(TMS) 3 , whose vapor pressure is 3.3 Â 10 À 1 Pa at 65-71 1C [21]. Also, AsPh 3 is less toxic (LD 50 in rats43200 mg kg À 1 ; 783 mg As kg À 1 [23]) than some other arsenic compounds such as As 2 O 3 (LD 50 in rats¼ 20 mg kg À 1 ; 15 mg As kg À 1 [24]) and AsH 3 (4 h LC 50 in rats¼42.6 ppm [25]). Wang et al reported that InAs NCs could be synthesized using solvothermal techniques by using AsPh 3 as the arsenic source [26,27].…”
