    摘要： Provided are a phosphor composition for a plasma display panel (PDP) including: a phosphor component which is composed of a zinc silicate-based phosphor represented by the formula of Zn 2 SiO 4 :Mn or of a mixture of the zinc silicate-based phosphor represented by the formula of Zn 2 SiO 4 :Mn and at least one further phosphor; and a continuous crystalline metal oxide layer composed of at least one positively charged metal oxide formed on the phosphor component, particularly composed of yttrium oxide (Y 2 O 3 ), and a PDP having a phosphor layer composed of the phosphor composition. The phosphor composition 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 composition is used to manufacture a green phosphor layer for a PDP, a green discharge voltage can be controlled to levels of red and blue colours due to a better surface charge property and a poor specific gradation discharge problem can be resolved.

    摘要翻译： 本发明提供一种用于等离子体显示面板（PDP）的荧光粉组合物，其包含：由式Zn2SiO4：Mn表示的硅酸锌系荧光粉或由所述硅酸锌系荧光粉表示的硅酸锌系荧光粉的混合物 Zn2SiO4：Mn和至少一种其他磷光体的配方; 以及由在荧光体成分上形成的至少一种带正电的金属氧化物（特别是由氧化钇（Y 2 O 3）构成）的连续结晶金属氧化物层和具有由该荧光体组合物构成的荧光体层的PDP。 用于PDP的荧光粉组合物具有由氧化钇等带正电的金属氧化物构成的连续的结晶层，因此具有更好的表面特性。 金属氧化物层起保护层的作用，以防止由于离子轰击造成的磷光体劣化。 当荧光粉组合物用于制造用于PDP的绿色荧光粉层时，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，并且可以解决不良的特定灰度级放电问题。
