摘要: 探索了从碳纳米管/纳米纤维(CNT/CNF)的制备到CNT/CNF阴极场发射平面显示器(c-FED)封装的工艺流程.用化学气相沉积方法,优化制备条件获得了纯度较高的CNT/CNF;以 CNT/CNF和低压荧光粉为原料,采用丝网印刷工艺制作显示器的阴极和阳极;采用类真空荧光显示器的封装工艺封装了c-FED样管.所研制的c-FED具有优良的场发射性能,较好的均匀性及发光密度,黄色荧光粉的c-FED在电场为 2.7 V/μm时的亮度可达600 cd/m2.因该显示器使用普通玻璃作为阴阳极基板,整个工艺流程在大面积和实用化方面有很好的应用潜力. 

Abstract: A process was developed for fabrication of diodetype carbon nanotube/nanofiber(CNT/CNF) field emission display (c-FED). The CNT/CNF was prepared by low pressure chemical vapor deposition. The anode and cathode were fabricated by screen printing of phosphor and CNT/CNF paste on glass plates. The vacuum package of the c-FED was fabricated like that of vacuum fluorescent display. The fully sealed c-FED exhibited a good emission property with a turnon field of 1.8 V/μm, and the emission current density of 1 mA/cm2 at 2.9 V/μm,the luminance of 600 cd/m2 for yellow light at on applied field of 2.7 V/μm, and uniform emission luminescence. The process has the advantages of low operating temperature compatible with glass substrates, a scalability in CNT/CNF yield and display size, and has a potential for practical application.

Key words: field emission display (FED), flat panel display, carbon nanotube/nanofiber (CNT/CNF), field emission display (FED), flat panel display
