摘要：

An intense green luminescent Na2Ca(PO4)F:Mn2+ phosphor has been prepared at high temperature by reduction treatment in a charcoal environment. The emission band of Mn2+ was obtained at around 522 nm (green) under 259 nm excitation. Enhancement in emission intensity arising from the thermal treatment is reported. The intense emission of the spectrum was assigned to electronic transitions T-4(1) -> (6)A(1) of Mn2+ ions. Intense PL emission suggested that temperature employed plays an important role in the present matrix. X-ray diffraction pattern, photoluminescence and morphology by SEM of the host lattice of phosphors at different temperatures have been reported in this paper. The results obtained show that the present phosphor has potential for application in green emitting phosphors for the lamp industry. Copyright (C) 2010 John Wiley & Sons, Ltd.
