Effect of synthesis method on photolumin- Escence properties of Na2Sr2Al2PO4Cl9:Ce3+ nanophosphor

Abstract

We have synthesized a series of single-composition emission Na2Sr2Al2PO4Cl9:Ce3+ phosphor by traditional solid state reactions and novel combustion method. Formation of compound was confirmed by X-ray diffraction analysis. The photoluminescence (PL) emission spectra were observed at 376 nm when excited around 322 nm for the various concentrations in both cases. The PL emission spectra of phosphors showed strong Ce3+ emission due to the 5d → 4f transition of Ce3+ ions. The Ce3+ emission intensity in Na2Sr2Al2PO4Cl9:Ce3+ prepared by combustion was higher than that of solid state reactions.
