    • Provided are a red light emitting phosphor, which has an improved efficiency in an ultraviolet or blue wavelength by increasing europium in the tungstate matrix and optionally adding samarium thereto, and a light emitting device comprising the same phosphor. The red light emitting phosphor has a composition represented by the formula of M_(2-x-y)Eu_(x)Sm_(y)WO_(6), wherein M is at least one element selected from the group consisting of Y, Al, Ga, and lanthanides, x is in the range of 0.2
    • 提供了一种红色发光荧光体,其通过增加钨酸盐基质中的铕和任选地向其中添加钐而具有提高的紫外线或蓝色波长的效率,以及包含相同荧光体的发光器件。 红色发光荧光体具有由M_(2-xy)Eu_(x)Sm_(y)WO_(6)表示的组成,其中M是选自Y,Al,Ga中的至少一种元素 和镧系元素,x在0.2 <= x <= 1.2的范围内,y在0 <= y <0.7的范围内。 磷光体在390-400nm波长带和450-480nm波长带中具有相对较强的吸收峰,在400-410波长带中具有另外的吸收峰。
