Thermolysis of Zn and Cd precursors under a non-coordinating one-pot wet-chemical synthesis has successfully produced a heterogeneous ternary Cd_xZn_1-xSe alloy with an extensive spectral red shift of 200nm in the visible range. Large yields of twenty milligram of the Cd_xZn_1-xSe alloy are minimally required for inclusion of the material in the active layer of an inorganic/organic photovoltaic device. The facile synthesis of such large yields of ternary semiconductor nanocrystal alloys has not commonly been reported in the literature. Herein we discuss first the thermolytic synthesis of the material beginning from the ZnSe core through the inclusion of the Cd-precursor. We then discuss the production of the ternary II-VI semiconductor Cd_xZn_1-xSe material through a process of non-coordinating synthesis with amine-activation to produce the high multi-milligram yields required for device inclusion.
