在稀土激活的Ca 2SnO 4化合物中寻找新的荧光材料，采用平行溶液法合成了一种新型的蓝色荧光粉Ca 2SnO 4：Ce，其发射强度达到了最好的商业Y3 Al 5 O 12：Ce 3+荧光粉的80%。在14种镧系元素激活的材料中，掺杂离子对磷光体的激发和发射性质的影响可以分为三类。此外，在A-Sn-O（A=Mg，Ca，Sr，和Ba）系统的潜在的磷光体进行了研究和Ca 2SnO 4被发现是最合适的主体化合物的镧系激活的磷光体。
In the search for new fluorescent materials among lanthanoid-activated Ca2SnO4 compounds, a parallel solution-based synthesis approach was applied and a new blue-emission Ca2SnO4:Ce phosphor was discovered; its emission intensity reaches 80% of the intensity of one of the best commercial Y3Al5O12:Ce3+ phosphors. Among 14 lanthanoid-activated materials, three categories could be distinguished with respect to the effect of the dopant ion on the excitation and emission properties of the phosphor. In addition, potential phosphors in the A–Sn–O (A=Mg, Ca, Sr, and Ba) systems were investigated and Ca2SnO4 was found to be the most suitable host compound for the lanthanoid-activated phosphors.
