N2 - The Y 2.9Ce 0.1Al 5O 12 (YAG: Ce 3+) phosphors were successfully prepared via molten salt synthesis (MSS) method using the eutectic mixtures of NaNO 2-KNO 2 or NaCl-KCl as the flux. Using NaCl-KCl as the flux, Y 3Al 5O 12 phase is formed above 1000°C, and the as-prepared YAG: Ce 3+ phosphor with 2 μm average particle size has good emission and excitation spectra. Using NaNO 2-KNO 2 as the flux, Y 3Al 5O 12 phase can be formed at a temperature as low as 400°C, but the as-prepared YAG: Ce 3+ phosphor with 200 nm average particle size do not have obvious emission and excitation spectra, and after being annealed at 1100°C, the powder also has 200 nm average particle size but has stronger emission and excitation spectra. Compared with the commercial YAG: Ce 3+ phosphor, the emission intensity of the phosphor prepared by MSS using NaNO 2-KNO 2 as the flux followed by calcination is a little low, but the latter has a smaller particle size, which will reduce the amount of phosphors utilized in white light-emitting diodes.
