    摘要： Disclosed are a phosphor in which prevention of aging deterioration of luminance and prevention of deterioration of discharging characteristics are compatible, a method of manufacturing the phosphor, and a plasma display panel manufactured by using the phosphor. A phosphor of the invention containing Mn as an activator is one with Mn serving as a major emission, wherein a ratio of an activator concentration in a superficial portion of a phosphor particle to an activator concentration inside the phosphor particle is 0.3-0.7.

    摘要： Disclosed is a method of preparing a phosphor which exhibits superior optical characteristics and improved resistance to deterioration, comprising the steps of subjecting a phosphor precursor obtained by a liquid phase process to a first calcination under an oxygen-containing atmosphere at a prescribed temperature and then subjecting the calcined phosphor precursor to a second calcination at a temperature lower than the temperature of the first calcination.
