摘要-测量了晶体MgO、MgO：Si、MgO：Sc和MgCaO的阴极发光（CL）发射，这些晶体通常用作PDP中的保护层材料。在这些材料中的一些中，发现UV发射带位于比文献中公开的波长更短的波长处，并且取决于杂质或掺杂的类型。发现MgCaO-球团材料含有单独的CaO相。结果表明，在大多数材料中，复合机制是热辅助的，而只有在MgO：Sc的情况下，发现隧穿复合。
Abstract— The cathode‐luminescence (CL) emission of crystalline MgO, MgO:Si, MgO:Sc, and MgCaO, often used as a protective‐layer material in PDPs, were measured. In some of these materials, it was found that the UV emission band is located at a shorter wavelength than published in the literature and depends upon the type of impurities or doping. MgCaO‐pellet material is found to contain a separate CaO phase. It is concluded that the recombination mechanism is thermally assisted in most of these materials, while only in the case of MgO:Sc tunneling recombination was found.
