一个简单的评估程序，这有利于最佳选择的电致发光荧光粉的基础上测量两个光学推导的能量吸收和发射。这两种能量被用作基于磷光体的经典构型坐标图模型的评价分析的输入。一个磷光体性能的品质因数提出了作为一个后果，制定本评估程序。然后使用该过程来合理化五种电致发光磷光体（ZnS：Mn、BaAl 2S4：Eu、SrS：Ce、SrGa 2S4：Ce、CaGa 2S4：Ce）的相对性能。此外，两个阴极射线发光磷光体（ZnS：Ag和ZnS：Cu）的评价使用这种方法，这表明该程序可能是一些实用程序在其他类型的磷光体的评价。
A simple assessment procedure is described which facilitates optimal selection of an electroluminescent phosphor based on the measurement of two optically deduced energies—absorption and emission. These two energies are used as input for an appraisal analysis based on a classical configuration-coordinate diagram model of the phosphor. A phosphor performance figure-of-merit is proposed as a consequence of the formulation of this assessment procedure. This procedure is then used to rationalize the relative performance of five electroluminescent phosphors (ZnS:Mn, BaAl2S4:Eu, SrS:Ce, SrGa2S4:Ce, CaGa2S4:Ce). Additionally, two cathodoluminescent phosphors (ZnS:Ag and ZnS:Cu) are appraised using this methodology, suggesting that this procedure may be of some utility in the evaluation of other types of phosphors.
