    Abstract: A cold-cathode fluorescent lamp that realizes high brightness and prolonged durability; and an electrode for this lamp. The electrode is composed of a substratum material and, laid on a surface thereof, a coating layer. The substratum material consists of a member selected from among nickel, a nickel alloy, iron and an iron alloy, so that shapes, such as a cup shape, can be easily formed. The coating layer includes a surface layer of tungsten or molybdenum and, disposed between the substratum material and the surface layer, a junction layer of zinc alloy. The tungsten or molybdenum, as compared with nickel and iron, is difficult in sputtering, is low in work function and has high melting point. By interposing the junction layer, the surface layer and the substratum material can be satisfactorily adhered to each other. The cold-cathode fluorescent lamp equipped with this electrode can reduce drop of brightness, wear of electrode, etc., so that the lamp realizes high brightness and prolonged durability.

    Abstract translation: 实现高亮度,延长耐用性的冷阴极荧光灯; 和该灯的电极。 电极由基材组成,并在其表面上铺设涂层。 基底材料由选自镍,镍合金,铁和铁合金的构件组成,从而可以容易地形成诸如杯形的形状。 涂层包括钨或钼的表面层,并且设置在基材和表面层之间,锌合金的接合层。 与镍和铁相比,钨或钼难以溅射,功函数低,熔点高。 通过插入接合层,可以令人满意地将表面层和基材材料彼此粘合。 配备有该电极的冷阴极荧光灯可以降低亮度的下降,电极的磨损等,使得灯实现高亮度和延长的耐久性。
