NOVEL CADMIUM SELENIDE COMPLEXES, PROCESS FOR PREPARING OF THEREOF, AND CDSE NANOPARTICLE

摘要

A cadmium selenide complex is provided to produce pure cadmium selenide nanoparticles useful for manufacturing cadmium selenide quantum dots at low temperature. A cadmium selenide complex has a structure represented by the formula 1 of Y-Cd-Se(CH2)mO(CH2)nO-R', wherein Y is a halogen element or C1-7 linear or branched alkyl, R' is a C1-7 linear or branched alkyl, and m and n are, independently of each other, 1-7. A method for preparing a cadmium selenide complex represented by the formula 2 of X-Cd-Se(CH2)mO(CH2)nO-R' includes the step of reacting a cadmium(II) halide compound represented by the formula 3 of CdX2 with a selenide alkali metal salt compound represented by the formula 4 of MSe(CH2)mO(CH2)nOR'. In the formulae 2-4, X is a halogen element, R' is a C1-7 linear or branched alkyl, m and n are, independently of each other, 1-7, and M is Li, Na, or K.
