首次采用固相反应法合成了BaZrSi 3 O 9，并观察到了蓝色余辉。合成的Ba_2O_3相在室温下暴露于紫外光后显示出清晰的蓝色持久发光，尽管没有任何镧系元素掺杂。提出BaZrSi_3O_9相的余辉是由于Ti ~（4+）作为杂质占据了畸变的八面体位置所致。
A blue afterglow was observed in the bazirite-type BaZrSi3O9 synthesized by a solid-state reaction for the first time. The synthetic bazirite phase showed a clear blue long-lasting luminescence at room temperature after the exposure of UV light, in spite of the free from any lanthanide-doping. It was proposed that the afterglow in the BaZrSi3O9 phase was originated from the occupation of Ti4+ as an impurity in the distorted octahedral site.
