Abstract
High after-grow intensity with controllable morphology SrAl2O4: Eu, Dy phosphors were synthesized by an innovative combustion-melted-salt-assistant-Sol-Gel (CMSASG) method, by using Oxides, Carbonate, Nitric acid, Polyethylene glycols and Urea as raw materials, Gel-forming at 100°C, Combustion under 450°C, Melted-salt-calcination at 1250°C. The luminescent intensity and after-grow intensity of the SrAl2O4: Eu, Dy phosphors with the suitable pair-dope synthesized by CMSASG method are higher than those of commercial samples. The size of the phosphor with excellent luminescent characteristics and shape of sphericity or near sphericity synthesized can be controlled from about 200 nm to 10 μm.
