Microwave-assisted synthesis and characterization of ZnO-nanorod arrays

High density ZnO-nanorod arrays （rod length 1.59 μm） were successfully synthesized via a microwave-assisted solution-phase method using zinc chloride and ammonia solution as reactants. The influence of concentration of ammonia solution, work power, and microwave irradiation time on the morphology an...

Description
Summary:High density ZnO-nanorod arrays （rod length 1.59 μm） were successfully synthesized via a microwave-assisted solution-phase method using zinc chloride and ammonia solution as reactants. The influence of concentration of ammonia solution, work power, and microwave irradiation time on the morphology and size of final products was carefully investigated. The crystal structure, chemical composition and morphologies of final products were characterized using X-ray powder diffraction （XRD）, scanning electron microscopy （SEM） and photoluminescence （PL）. The as-synthesized ZnO is composed of single crystalline and possesses three photoluminescence emissions centered at 400, 469 and 534.5 nm, respectively.
