초록
Blue-emitting divalent europium-activated strontium magnesium orthosilicate (Sr3MgSi2O8 :Eu2+) oxide phosphor was synthesized through a low-temperature chemical solution process using tetraethyl orthosilicate and inorganic salts as starting materials. The transparent sol was preheated at 300 oC for 120 minutes and then the precursor was finally annealed at 900 oC for 240 minutes. Crystallinity, surface morphology and luminescent properties have been investigated. The phosphor emits blue luminescence with a peak wavelength at 457 nm under near-ultraviolet excitation at 365 nm.
