The synthesis of similar compounds to Ca₂Eu₈ (SiO₄) ₆O₂ in MO-SiO₂-Ln₂O₃ (M = Ca, Sr, Ba, Ln = lanthanide) system were investigated and their luminescent properties were studied. In MO- SiO₂-Eu₂O₃ system, it existed in one phase area of the compound that took the apatite structure. This compound was shown by M_mEu_n (SiO₄) ₆O_x (2m=12-n, x=n-6). The range of composition of this compound was 6-9 as n in all alkaline earth system. The emission intensity has changed greatly though the same structure is taken in this composition area. The possibility of existence of compound M₂Ln₈ (SiO₄) ₆O₂ was examined. As a result, the same crystal structure was formed with all lanthanide elements in the Ca system and the lanthanide elements without Yb in the Sr system. This compound of the apatite structure possesses the high stability of a crystal structure for the kind and the composition change of the element, and seems for the possibility with an interesting characteristic to exist like this by variously examining the kind of the element and the amount.
