Alloyed semiconductor nanocrystals (NCs) are of
great interest because introducing additional elements
within NCs can significantly affect NC properties
including the ability to tune band gaps, enhance
absorbance coefficients, minimize intrinsic or surface
defects, make crystals structure more stable, and/or
control NC size/structure (Xie et al. 2005; Bae et al.
2009; Gaponik et al. 2010). Improved properties of
alloyed NCs can bring about more efficient applications
in electronic lighting and displays (Sarkar et al.
2011), photovoltaic devices (McDaniel et al. 2013),biosensing/imaging (Liang et al. 2009), etc. Moreover,
synthetic approaches of alloyed NCs that are amenable
to large-scale production are needed in many applications
such as the manufacture of light-emitting diodes
(LED) and solar cells (Kim et al. 2012).
Recently, chalcopyrite semiconductor copper–
indium–sulfide (Cu–In–S or CIS) NCs have gained
