中文摘要	a blue emitting sr2ceo4 phosphor with a one-dimensional structure has been prepared by a two-step spray pyrolysis (sp) method, starting from the aqueous solutions of metal nitrates with citric acid and polyethylene glycol (peg) as additives. the material is ultimately designed for field emission displays (feds). x-ray diffraction (xrd), thermogravimetric and differential thermal analysis (tg-dta), field emission scanning electron microscope pictures (fe-sem) as well as photoluminescence (pl) and cathodoluminescence (cl) spectroscopy and lifetime measurements have been employed to characterize the samples. the morphology, pl and low voltage cl properties of sr2ceo4 phosphors as-prepared using the sp method have been investigated by changing the concentration of the precursor solution, concentration of peg, annealing temperature, acceleration voltage and filament current. the obtained sr2ceo4 phosphor particles are spherical and of submicron size, 0.5-2 mu m. the emission spectrum of the phosphors shows a broad band with maximum at 467 nm (lifetime = 37.4 mu s; cie chromaticity coordinates: x = 0.15 and y = 0.21), presumably due to a ligand-to-metal charge-transfer transition.
