在某些情况下，用铜活化ABPO 4型正磷酸盐得到有效的磷光体。发现的最亮的磷光体是SrLiPO，-Cu和BaLiPO，-Cu，分别在4150和4600 A处具有发射峰（具有2537 A激发）。还研究了ABPO型正磷酸盐分别与两种碱土金属或碱金属离子的性质。在过去的几年中，发表了几篇关于铜激活荧光粉的论文。Uehara、Kobuke和增田（1）描述了铜活化的正磷酸钙和相关磷光体的制备和发光特性，Wanmaker和Bakker（2）研究了改性的正磷酸锶。Hunt和McKeag（3）发表的一篇论文中给出了铜和锡活化卤代磷酸盐的性质。用铜活化的磷酸钍在2537 A辐射激发时显示出黄橙色发射（4）。在随后的专利中，该磷光体在低压汞放电灯中的应用被给出，其中添加了磷酸二铵或磷酸（5）。此外，还发表了一些关于这种磷光体更基本性质的论文。Maeda（6）报道了正磷酸钙中铜中心的构型坐标曲线。Uehara（7）对同一种磷光体的发光特性给出了定量解释。
Activation of orthophosphates of the type ABPO4 with copper gives an efficient phosphor in some cases. The brightest phosphors found are SrLiPO,-Cu and BaLiPO,-Cu, with an emission peak (with 2537A excitation) at 4150 and 4600A, respectively. The properties of orthophosphates of the type ABPO, with two kinds of alkali earth or alkali metal ions, respectively, were also studied. X-ray diagrams of the compounds investigated are given.During the past few years several papers concerning copper-activated phosphors have been published. Uehara, Kobuke, and Masuda (1) described the preparation and luminescent properties of copperactivated calcium orthophosphates and related phosphors, and Wanmaker and Bakker (2) investigated modified strontium orthophosphates. The properties of copper-and tin-activated halophosphates were given in a paper published by Hunt and McKeag (3). Thorium phosphate activated with copper shows a yellow-orange emission when excited by 2537A radiation (4). In a subsequent patent the application of this phosphor in low-pressure mercury discharge lamps is given, with the addition of diammonium phosphate or phosphoric acid (5). Moreover, some papers were published concerning the more fundamental properties of this kind of phosphor. The configurational coordinate curve for the copper center in calcium orthophosphate was reported by Maeda (6). Uehara (7) has given a quantitative interpretation of the luminescent properties of the same phosphor.
