研制了一种新型荧光粉Y（4）Al（2）O（9）：Eu（3+）（YAM：Eu（3+）），该荧光粉在真空紫外（VUV）和紫外（UV）激发下可发出612 nm的强单色红光，可用于下一代等离子体显示器（PDP）。与市售的（Y，Gd）BO（3）：Eu（3+）红色PDP荧光粉相比，该荧光粉具有更好的发光效率、色纯度和更短的衰减时间。YAM：Eu（3+）在VUV激发下具有高的色纯度（x = 0.67，y = 0.32）、短的衰减时间（1.03 msec）和在PDP面板制备过程中优异的抗降解稳定性，这表明YAM：Eu（3+）是当前和未来PDP的潜在候选者。通过SiO（2）的表面包覆进一步改善了磷光体的特性。
A new phosphor Y(4)Al(2)O(9):Eu(3+) (YAM:Eu(3+)) emitting intense monochromatic red at 612 nm under vacuum ultraviolet (VUV) and ultraviolet (UV) excitations has been developed for application in next generation plasma display panels (PDPs). The developed phosphor has better luminescence efficiency, colour purity and shorter decay time than commercial (Y,Gd)BO(3):Eu(3+) red emitting PDP phosphor. High color purity (x = 0.67, y = 0.32) under VUV excitation with short decay time (1.03 msec) and excellent stability against degradation during PDP panel preparation suggest that YAM:Eu(3+) is a potential candidate for present and future PDPs. Surface coating by SiO(2) further improved phosphor characteristics.
