摘　　要：Experimental data on cathodeluminescence of 34 individual specimens of naturallyoccurring apatite differring in the mode of occurrence are presented in this paper.In accordance with the characteristic distribution of the bands and lines of apatite specimens,it has been confirmed that RE ions Sm^2+,Dy^3+,En^2+,etc.,are the main activators for the cathodeumineseence of apatite.In conjunction with the crystallological study.a priliminary investigation into the mechanism for apatite cathodelnminescence has been made as well.The author has suggested that the cathodelumineseence of apatite may be attributed to the replacement of Mn at the site of Can by Mn^2+,and the luminous colour seems to have no direct,simple correlation with that of the crystal itsself.Experimental data on cathodeluminescence of 34 individual specimens of naturally-occurring apatite differring in the mode of occurrence are presented in this paper. In accordance with the characteristic distribution of the bands and lines of apatite speci-mens, it has been confirmed that RE ions Sm3+, Dy3+, Eu2+, etc., are the main activators for the cathodeuminescence of apatite. In conjunction with the crystallological study, a priliminary investigation into the mechanism for apatite cathodeluminescence has been made as well. The author has suggested that the cathodeluminescence of apatite may be attributed to the replacement of Mn at the site of CaII by Mn2+, and the luminous colour seems to have no direct, simple correlation with that of the crystal itsself.
