CsI nanoparticles were introduced to ZnO-CNTs composite field emitters through screen-printing process. Enhanced field emission properties were obtaind after coating or mixing CsI during ZnO-CNTs composite emitters fabrication. Further improved field emission properties from CsI-mixed ZnO-CNTs emitters are observed, and a low turn on electric field of 1.6V/um is achieved.
In this study, we fabricated a cathode using screen printing method with carbon nanotubes and ZnO nanotetrapods as cathode emission materials and CsI nanoparticles as coating materials. After several comparative experiments, we find that 3g CsI dispersed into an organic paste which is composed of 20ml terpineol and 1g ethyl cellulose has significant results to improve the performance of the field...
A simple and cheap way to fabricate large area ZnO nanoemitter cold cathode was introduced. The properties of the cold cathode were characterized. The potential application of the cold cathode in flat panel light source was also discussed.
Using the tunneling effect under high electric field, field emission cold cathode could obtain an emission current which is large enough. In this paper, we reported the large field-emission from CNTs and ZnO tetrapods composited field emitters. Screen-printing method is used in our experiment and more than 15 mA field-emission current is obtained with 0.5 mm gap.
The field-emission cathode has potential application in the field emission display panels, high frequency amplifiers, X-ray sources, cathodoluminescent light sources. In a field-emission display device, the field-emission has to be modulated sensitively. Therefore, a few kinds of field-emission triode, such as normal-gate, under-gate and lateral-gate have been proposed. To simplify the fabrication...
As we know, the unsatisfactory field emission from the films by electrophoresis is resulted from the weak adhesion. The main aim of this paper is to improve the adhesion surrounding electrophoresis technologies. In addition, A simple controllable method is reported for the coating of ZnO nanowires with Ag nanoparticles and ZnO/Carbon nanotubes (CNT) composite.
As we know, the unsatisfactory field emission from the films by electrophoresis is resulted from the weak adhesion. The main aim of this paper is to improve the adhesion surrounding electrophoresis technologies. The technique we applied is referred to employ both organic binders and inorganic solution simultaneously. In addition, the influences of the applied voltage, inter-electrode distance and...
