Abstract: | In the context, SrxY10−x(SiO4)y(PO4)6−yO2 doped with 1 mol%Eu3+ (x = 2, y = 6; x = 4, y = 4; x = 5, y = 3; x = 8, y = 0) were synthesized by using 3-aminopropyl-triethoxysilane (APES) as the sources of the silicate network. X-ray diagrams confirm that SrxY10−x(SiO4)y(PO4)6−yO2: Eu3+ solid solutions are formed as a pure apatitic phase. The SEM picture shows that there exist some novel unexpected coral like morphological structures. The luminescent intensity is the strongest for the host composition of Sr4Y6(SiO4)4(PO4)2O2 although the effect of the composition on the luminescent intensity is little. |
