In order to evaluate the performance of ZnO nanowire field emission display under different temperature, the temperature dependence of field emission current of a fully-sealed diode-structured field emission device using ZnO nanowire cold cathode was studied when the temperature changed from −60°C to 80°C. The pressure inside the device was also measured. It is found that the emission current decreases...
The vacuum level inside a FED device significantly influences the performance of the field emitters. In order to investigate the pressure inside a fully-sealed FED, and in particular to monitor the pressure in situ during the aging process, an ion gauge was integrated to the device. The pressure inside the device was measured during the sealing process and after activation of getters. The pressure...
Cathodoluminescence (CL) properties of SrGa2S4 :Eu2+ phosphor synthesized by high temperature solid phase reaction have been presented at 0~10 kV and 0~100 muA/cm2 . Photoluminescence (PL), CL and X-ray photoelectron spectroscopy (XPS) spectra were measured for phosphors before and after bombardment with high current densities. PL and CL spectra show that the commercial green phosphor ZnS: Cu, Au,...
Field emission display (FED) as one of the next generation display technologies, has attracted the attentions of many researchers. Preparation of low cost cold cathode material for FED application is the topic that attracts much attention in this area. In this paper, the vacuum gap dependence of field emission characteristics of polymethyl methacrylate (PMMA) polymer thin film were observed. The observed...
