“…The most intense lines near 575 nm may be unambiguously interpreted as a pure electronic transition 5D0 -ł 7F0. Its strong relative intensity and unusually high position are similar to those detected in fluorapatite and oxyapatite [4,13].…”

The purpose of this work was identification of luminescent lines occurring in natural carbonate-fluor-apatite (francolite) mineral. For identifrcation of several rare earth ions occurring in natural francolite, the lu -m i n e s c e n c e o f r a r e e a r t h i o n s w a s e x t e n s i v e l y s t u d i e d i n a r t i f i c i a l m i n e r a l consisting of a pure francolite (not containing rare earth) of the composition Ca5(PO4)3(F,O):Ca5(PO4)3CO3 activated with Pr, Eu and Sm ions and then compared with the huminescence features observed in natural mineral.

“…Since the ionic radii of Sr 2+ ions (r VII = 1.21Å, r IX = 1.31Å) are larger than Eu 3+ ions, for Eu 3+ to replace Sr 2+ ions the charge compensating mechanism must be considered. For substituting Sr 2+ , the formation of one vacancy per pair of incorporated Eu 3+ ions were involved and therefore the following process introduced [23]:…”
