    Abstract: PURPOSE: A production method for oxynitride and nitride phosphors is provided to enable use for displays such as vacuum fluorescent displays(VFDs), field emission displays(FEDs) and LED display devices. CONSTITUTION: A production method for oxynitride and nitride phosphors comprises the steps of: dipping an aqueous solution including a metal source for forming oxynitride phosphors and silicon(Si) source in an organic polymer to obtain a first precursor; and plasticizing the first precursor at 800-1800 °C in a nitrogen-containing atmosphere to prepare oxynitride-based phosphor powder.
