PROBLEM TO BE SOLVED : To provide a red phosphor for a PDP, which has high color purity. SOLUTION : The red phosphor for a PDP is a trivalent europium (Eu3+) activated rare earth borate phosphor, which is represented by YBO3 : Eu3+or (Y, Gd)BO3 : Eu3+with at least a neodymium (Nd) compound attached thereto. The attachment of a neodymium (Nd) compound such as neodymium vanadate (NdVO4) brings about a phosphor with high emission luminance, a long life, and high color purity.
