现有的粉末EL理论被证明无法解释本工作第一部分中描述的电致发光条纹或线条的新发现。几个新的假设进行了讨论。其中，一个模型似乎是可能的，它是基于从导电缺陷线的相对端到绝缘微晶的同时双极场发射，与激活剂中心注入的空穴的捕获，并在场反转时与移动的电子复合。文中对该模型进行了详细的讨论，并证明了该模型的合理性。一个新的碰撞电离模型也被描述，这是非常相似的场使命模型。目前，它在实验上与场致发射模型无法区分。
Existing theories of ‐powder‐EL are shown to be unable to explain the new findings of electroluminescent striations or lines described in Part I of this work. Several new hypotheses are discussed. Among these, a model seems to be likely which is based on simultaneous bipolar field‐emission from opposite ends of conducting imperfection lines into the insulating crystallite, with trapping of injected holes in activator centers, and recombination with mobile electrons at field‐reversal. This model, which is shown to be consistent with facts, is discussed in detail. A new impact ionization model is also described which is very similar to that of the field‐mission model. At present, it is experimentally indistinguishable from the field‐emission model.
