    • A field emission device (10) includes a sealed container (12) with a light permeable portion (120). A phosphor layer (14) and a light permeable anode (16) are coated on inside surface of the light permeable portion in succession. A cathode (18) is enclosed in the sealed container. A carbon nanotube yarn is attached to the cathode facing the light permeable portion. Before being embedded into the sealed container, the carbon nanotube yarn is processed in the following steps: providing a carbon nanotube array, drawing out at least one carbon nanotube yarn string from the carbon nanotube array, treating the at least one carbon nanotube yarn string using an organic solvent in a manner such that the at least one carbon nanotube yarn string is formed into a single strand of carbon nanotube yarn, and heating the single strand of the carbon nanotube yarn.
    • 场致发射装置(10)包括具有透光部分(120)的密封容器(12)。 荧光体层(14)和透光阳极(16)依次涂覆在透光部分的内表面上。 阴极(18)封装在密封容器中。 将碳纳米管丝附接到面向透光部的阴极。 在嵌入密封容器中之前,以下列步骤处理碳纳米管纱线:提供碳纳米管阵列,从碳纳米管阵列中抽出至少一个碳纳米管纱线串,使用 有机溶剂,使得至少一个碳纳米管纱线串形成单股碳纳米管纱线,并加热碳纳米管纱线的单股。
