The single crystal and crystallized powder of triphosphate CeP 3O9have been synthesized, and the space group of CeP 3O9 has been determined to be C2221 with the cell parameters of a = 8.6059, b = 11.2437, c = 7.3518 Å, V = 711.4(3) Å3, Z = 4, D, = 3.520 g/cm3, F(000) = 700, R = 0.0377 and wR = 0.0930. The absorption and emission spectra have been measured, for which the strongest absorption and emission peaks are located at 280 and 320 nm, respectively. The density of state (DOS) and dielectric function have been calculated by the DFT method. The crystal is transparent provided the wavelength is larger than 341 nm, and the observed ultraviolet cut-off edge is at about 350 nm for a polycrystalline power sample. It is possible that the triphosphate CeP3O9 will become an ultraviolet emission material.
