摘要：

通过高温固相法制备了系列Ba2ZnW1–xMoxO6:Eu3+,Li+红色荧光粉，研究了Mo6+离子掺杂对样品的晶体结构以及荧光性能的影响。结果表明：部分Mo6+离子取代W6+离子后，样品的激发波长发生红移，最大激发波长从316 nm转移到373 nm，使得样品能有效地被近紫外光(350～420 nm)激发。Ba2ZnW0.6Mo0.4O6:Eu3+, Li+在373 nm波长的激发下，所得的荧光强度最强。Eu3+离子的特征跃迁仍以5D0→7F1(598 nm)跃迁为主，但5D0→7F2(615 nm)跃迁得以加强。通过其发射光谱计算所得色坐标为(0.6385, 0.3611)，接近标准红色色坐标。Ba2ZnW0.6Mo0.4O6:Eu3+, Li+作为红色荧光粉在被近紫外激发的白光LED中具有很好的应用前景。
