    摘要： Provided are a phosphor for a plasma display panel (PDP) including: a zinc silicate-based phosphor represented by the formula of Zn2SiO4:Mn; and a continuous crystalline metal oxide layer composed of yttrium oxide (Y2O3) formed on the zinc silicate-based phosphor, and a PDP having a phosphor layer composed of the phosphor. The phosphor for a PDP has a continuous crystalline layer composed of a positively charged metal oxide such as yttrium oxide, and thus has better surface properties. The metal oxide layer acts as a protecting layer to prevent deterioration of the phosphor due to ion bombardment. When the phosphor is used to manufacture a green phosphor layer for a PDP, a green discharge voltage can be controlled to levels of red and blue colors due to a better surface charge property and a poor specific gradation discharge problem can be resolved.

    摘要翻译： 提供了一种用于等离子体显示面板（PDP）的荧光体，其包括：由以下结构式表示的硅酸锌基荧光体：Zn 2 SiO 4·Mn：Mn; 以及由在硅酸锌系荧光体上形成的氧化钇（Y 2 O 3 O 3）构成的连续的结晶金属氧化物层，以及具有由 磷。 PDP的荧光体具有由带正电的金属氧化物如氧化钇构成的连续结晶层，因此具有更好的表面性能。 金属氧化物层起保护层的作用，以防止由于离子轰击引起的荧光体的劣化。 当使用荧光体制造用于PDP的绿色荧光体层时，由于更好的表面电荷特性，可以将绿色放电电压控制为红色和蓝色的水平，并且可以解决差的特定等级排出问题。
