红光荧光材料及其制造方法、及白光发光装置
摘要：
一种红光荧光材料，适于受到第一光线激发而放射出红光。此红光荧光材料的特征在于具有下列式(1)的化学式，A2Eu(MO4)(PO4)-式(1)；其中，A表示锂(Li)、钠(Na)、钾(K)、铷(Rb)、铯(Cs)或银(Ag)；M表示钼(Mo)、钨(W)或钼与钨的组合(MoxW(1-x))。此红光荧光材料可提供高辉度与良好色纯度的红光。此外，由于此红光荧光材料的组成为氧化物，所以，此红光荧光材料具有良好的化学稳定性及长的使用寿命。
摘要（英）：

The invention relates to a red light luminescent material which can be excited by a first ray to emit red light. The red light luminescent material is characterized by having a chemical formula as shown in the following formula (1): A2Eu(MO4)(PO4)-formula (1), wherein A represents lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) or silver (Ag); and M represents molybdenum (Mo), tungsten (W) or a combination of molybdenum and tungsten (MoxW(1-x)). The red light luminescent material can provide red light with high luminance and fine color purity. Besides, since the components of the red light luminescent material are oxides, the red light luminescent material has favorable chemical stability and long service life.
