Synthetic strategy of porous ZnO and CdS nanostructures doped ferroelectric liquid crystal and its optical behavior

A simple and scalable chemical approach has been proposed for the generation of 1-dimensional nanostructures of two most important inorganic materials such as zinc oxide and cadmium sulfide. By controlling the growth habit of the nanostructures with manipulated reaction conditions, the diameter and uniformity of the nanowires/nanorods were tailored. We studied extensively optical behavior and structural growth of CdS NWs and ZnO NRs doped ferroelectric liquid crystal Felix-017/100. Due to doping band gap has been changed and several blue shifts occurred in photoluminescence spectra because of nanoconfinement effect and mobility of charges.

► CTAB assisted CdS nanowires prepared having uniform diameter of 65 nm.
► Hydrazine monohydrate assisted ZnO nanorods having uniform length of 2000–4000 nm.
► The mixed band gap of CdS–Felix is increased by ΔEg = 0.35 eV.
► The mixed band gap of ZnO–Felix is decreased by ΔEg = −0.22 eV.
► Interesting features from photoluminescence behavior of such hybrid structure.
