Raman spectroscopic study of the phosphate mineral churchite-(Y) YPO4.2H2O
Original language description
Raman spectroscopy has been used to study the rare-earth mineral churchite-(Y) of formula (Y,REE)(PO4). 2H2O. The mineral contains yttrium and, depending on the locality, a range of rare-earth metals. The Raman spectra of two churchite-(Y) mineral samples from Jachymov and Medvedin in the Czech Republic were compared with the Raman spectra of churchite-(Y) downloaded from the RRUFF data base. The Raman spectra of churchite-(Y) are characterized by an intense sharp band at 975 cm-1 assigned to the nu1 (PO43-) symmetric stretching mode. A lower intensity band observed at around 1065 cm-1 is attributed to the nu3 (PO43-) antisymmetric stretching mode. The (PO43-) bending modes are observed at 497 cm-1 (nu2) and 563 cm-1 (nu4).
