ZnSe nanorods are grown by varying the amount of reducing agent Sodium borohydride and keeping the amount of zinc chloride, selenium powder constant. The samples are characterized using electron diffraction techniques. Simultaneously optical absorption, photoluminescence and longtime photorelaxation of these samples are studied at room temperature. An increase in band gap is observed in each case as compared to bulk ZnSe. Also the formation of nanorods is found to be favourable at particular ratio of reducing agent. An attempt is made to explain the growth and correlate the structural, optical and electrical properties.
