Cerium-containing tricalcium phosphate (TCP, Ca3(PO4)2) nanopowders with the whitlockite structure have been prepared via precipitation from solution. After heat treatment at 1300°C, the materials contained 0, 0.07, 0.18, and 0.39 wt % cerium, which corresponded to х = 0, 0.0025, 0.006, and 0.013 in the general formula Ca3 –хCe2х/3(PO4)2. The thermal stability of β-TCP has been shown to increase with increasing cerium content. The synthesized cerium-containing TCP powders show luminescence properties under excitation at wavelengths from 270 to 320 nm, with a peak emission wavelength from 360 to 390 nm, characteristic of Ce3+ luminescence. Varying the percentage of cerium in the materials and heat treatment temperature causes the emission spectrum to shift. [ABSTRACT FROM AUTHOR]
