    Abstract: A method for preparing oxide nano phosphors is provided to ensure a simple and economical process because of not needing expensive materials and facilities, and to synthesize the oxide nano phosphors with uniform particle size distribution. A method for preparing oxide nano phosphors comprises the steps of preparing a metal precursor solution; impregnating porous polymer materials in the metal precursor solution; and heat-treating the porous polymer material containing the metal precursor solution. The heating process heats the porous polymer material containing the metal precursor solution at a heating rate of 100 ‹C or more per minute to 500 ‹C or more.
