Abstract Eu2+-activated Ca3ZrSi2O9 (Ca3ZrSi2O9:Eu2+) phosphors were successfully synthesized by an amorphous metal complex method with the use of propylene glycol-modified silane. We studied the photoluminescence and crystallographic properties of Ca3ZrSi2O9:Eu2+ as a function of total Eu content (x) in Ca3−xEuxZrSi2O9. The Ca3ZrSi2O9:Eu2+ samples with low Eu2+ contents (x = 0.003–0.030) had a green emission peak at 520 nm. However, when the Eu2+ content (x) was increased to 0.300, Ca3ZrSi2O9:Eu2+ had a red emission peak at 640 nm and the green emission disappeared. The resulting red emission is mainly attributed to Eu2+ occupying different crystallographic sites of the Ca-O polyhedra of the Ca3ZrSi2O9 lattice.

一种新型 Eu2+ 活化的钙锆硅酸盐荧光粉：Ca3ZrSi2O9:Eu2+

摘要 以丙二醇改性硅烷为原料，采用非晶金属络合物法成功合成了Eu2+活化的Ca3ZrSi2O9（Ca3ZrSi2O9:Eu2+）荧光粉。我们研究了 Ca3ZrSi2O9:Eu2+ 的光致发光和晶体学特性，作为 Ca3−xEuxZrSi2O9 中总 Eu 含量 (x) 的函数。具有低 Eu2+ 含量 (x = 0.003–0.030) 的 Ca3ZrSi2O9:Eu2+ 样品在 520 nm 处具有绿色发射峰。然而，当 Eu2+ 含量 (x) 增加到 0.300 时，Ca3ZrSi2O9:Eu2+ 在 640 nm 处出现红色发射峰，绿色发射消失。产生的红色发射主要归因于 Eu2+ 占据 Ca3ZrSi2O9 晶格的 Ca-O 多面体的不同结晶位置。
