Synthesis and temperature Effect of ZnO nanoparticle seeding layer and nanorods

Abstract

Zinc oxide nanostructured with different seeding layer annealing temperature have been synthesized by drop casting technique on FTO coated glass substrate. The optimized seeding layer have employed to synthesis ZnO nanorods were growth aqueous solutions method of zinc nitrate and HML as precursors with different growth temperatures. FESEM supported by EDS results showed significant information of ZnO topographic surface. X- Ray diffraction scan demonstrate a hexagonal wurtzite structure with c-axis orientation of the ZnO nanorods. Strong ultraviolet (UV) emission of ZnO nanorods has detected by UV visible measurement. The obtained results have analyzed optimize annealing temperature of ZnO seeding layer and suitable growth temperature of ZnO nanorods, with crystal hexagonal ZnO nanorods and homogenous distribution with 95°C growth temperature
