Abstract

A facile synthetic strategy toward passivating Cd_1-xZn_xSe_1-yS_y shell on CdSe core nanoplatelets (NPLs) with a graded chemical composition gradient was introduced via a one-pot synthesis approach by capitalizing on the difference of chemical reactivity between cadmium oleate and zinc oleate precursors. Plain CdSe NPLs were first synthesized and then followed by precise passivation with the graded Cd_1-xZn_xSe_1-yS_y shell. The effect of precursor solubility on the morphology of NPLs was corroborated by transmission electron microscopy characterization. The photophysical properties of NPLs were explored using a UV–vis spectrometer and a spectrofluorometer.
