Abstract

The Red-emitting phosphors of Eu3+ activated phosphate based phosphors prepared by combustion synthesis, characterized by XRD (X-ray diffraction), SEM (Scanning electron microscopy) and Photoluminescence (PL) techniques, has been reported. The luminescence properties were investigated by photoluminescence excitation and emission spectra. PL excitation spectrum of CaAl3(PO4)3F2:Eu3+ phosphors shows the excitation peaks ranging from 370 to 400 nm due to 4f→4f transitions of Eu3+ ions. PL emission spectrum of Eu3+ ion under 394 nm excitation gives PL emission at 615 nm (red) due to 5D0 7F2 transitions, 593 nm (orange) emission due to 5D0  7F1transitions. Hence PL emission in trivalent europium may be efficient photoluminescent materials for solid-state lighting phosphors.
