- We report on a simple route for the production of uniform and ultra narrow wurtzite CdS nanowires and nanorods. The nanorods are medium friendly (can exist in organic and aqueous phase) thus making them flexibly suitable for various applications. The centimeter range switchable ordering of the nanowires/rods into 3D microstrings by application of low magnitude DC electric field simply via two graphite electrodes is demonstrated. More sophisticated electrodes can be used for the same system to achieve more complex and fine patterns that can find potential use in nanoelectronics. The aligned microstrings (also wires/rods) show strong polarization dependence along their long axes. The polarized emission with respect to the unique c-axis makes the system suitable for orientation sensitive devices.
