Abstract:

A series of novel Ce3+-doped manganese phosphite (NH44[Mn4-xCex(HPO36](JIS-10∶Ce3+) inorganic open-framework materials was prepared under ionothermal conditions. The synthesized compounds were characterized by means of powder X-ray diffraction(PXRD), scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS), X-ray photoelectron spectroscopy(XPS), Fourier transform infrared (FTIR) spectroscopy and photoluminescence(PL) spectroscopy. The influences of Ce3+ doping concentration, reaction temperatures and reaction time on the luminescence property were studied under 260 nm excitation. A green emission band at 500 nm of Ce3+ and a yellow emission band at 590 nm of Mn2+ were observed. At low doping level of 0.06 Ce3+, the phosphor had a yellow-green emission with the CIE coordinate of (0.38, 0.48). The green emission band grew more dramatical than the yellow one when the doping concentration of Ce3+ ion was increased, leading to the tunable color-emission. The excitation competition between Ce3+ and Mn2+, as well as the energy transfer between these species were also studied. The strongest emission was observed at x=1.33, higher than which concentration quenching occurred.
