Hexagonal cone-shaped ZnO nanomaterial were synthesized by the esterification with zinc acetate and ammonia water. By the test methods of XRD and SEM etc.
the preparation condition
field emission performance and stability of nanometer zinc oxide thin film were studied.The experimental results indicated that the pyramidal nanometer zinc oxide prepared by hydrothermal method has the good field emission performance
and is the ideal material for FED negative pole.
