Ca3(PO4)2:Eu(3+) phosphor was prepared using a facile chemistry method in the presence of surfactants. The effects of surfactants on the morphology and photoluminescence properties of Ca3(PO4)2:Eu(3+) phosphor were investigated. The morphology of the phosphor was significantly influenced by the surfactants employed. When nonionic surfactant glyceryl monostearate and anionic surfactant sodium dodecylbenzene sulfonate were employed, the phosphor powders are composed of a large number of homogeneous spherical particles with sizes of 0.3-0.6 µm and 2-3 µm, respectively. By contrast, when cationic surfactant cetyltrimethylammonium bromide was used, the morphology of the phosphor is completely different. The product is an excellent cuboid, and the phosphor prepared with 2.5 mmol cetyltrimethylammonium bromide showed higher luminescent intensity than phosphors prepared with the other two types of surfactants.
采用简便的化学方法在表面活性剂存在的条件下制备了Ca3(PO4)2:Eu(3+)荧光粉。研究了表面活性剂对Ca3(PO4)2:Eu(3+)荧光粉的形貌和光致发光性能的影响。所用表面活性剂对荧光粉的形貌有显著影响。当使用非离子表面活性剂单硬脂酸甘油酯和阴离子表面活性剂十二烷基苯磺酸钠时，荧光粉粉末分别由大量尺寸为0.3 - 0.6 µm和2 - 3 µm的均匀球形颗粒组成。相比之下，当使用阳离子表面活性剂十六烷基三甲基溴化铵时，荧光粉的形貌完全不同。产物是一种优良的长方体，用2.5 mmol十六烷基三甲基溴化铵制备的荧光粉比用其他两种类型表面活性剂制备的荧光粉具有更高的发光强度。
