چکیده انگلیسی
A blue phosphor, europium doped barium magnesium aluminate (BaMgAl10O17:Eu2+) 200-300Â nm in size, has been synthesized via a solution phase method using a mixture of metal hydroxide with metal chloride as the precursor source. A water-soluble polymer of high molecular weight was used in the synthesis process. The effects of polymer media and heating treatments on the physical and optical properties such as crystallinity and photoluminescence of particles were investigated. Activation of the luminescence center under a reducing atmosphere has been accomplished concurrently with crystal growth. Photoluminescent (PL) emission spectra of particles centered around 450Â nm when using a 254Â nm excitation wavelength. The polymer potentially prevents agglomeration and enhances the PL emission of the particles.
