Colloidal nanostructured materials are promising for applications in optoelectronic devices. Beyond size-tuning as in quantum dots, shape-tuning of the material at the nanometer scale also results in novel optical and electronic properties. The applications demand high quality and structure-well-controlled materials, which is still underdeveloped. We have synthesized PbSe nanorods in wide temperature range 110-170 °C and different growth times from 25 sec to 5.5 minutes. Here we report the effect of chloroalkane co-solvent which is added during the synthesis drives the one dimensional growth of nanocrystals to form nanorods. It is seen that growth time and growth temperature also plays an important role on the control over size of nanorod formed. The photoluminescence, absorption and TEM measurements done on different samples taken at different reaction conditions shows that we have good control over size. The single exponential decay of PL life time for these rods indicates the high quality rods can be synthesized by this procedure.
