ABSTRACT:
Li+ co-activated Ba5(PO4)3Cl:Eu3+ generally called halo-apatite were prepared by solution method using ethylene glycol at low temperature (150 oC). Different Ba compounds such as BaHPO4 and Ba5(PO4)3Cl were observed in this preparation process when the pH of the synthesis medium changed from pH 6 to 11.5. The prepared samples showed the five main emission peaks at 483, 592, 615, 652 and 698 nm; and with increasing pH value from 6 to 11.5 the emission intensity increases. The material can show the white, blue and yellowish-green emission colors when the sample was excited at different excitation wavelengths from 233 to 393 nm.
