Self-activated phosphors have attracted considerable attention due to their low synthesis temperature, high excitation threshold, and broad emission spectrum. And self-activated tungstate are distinguished by cost stable chemical properties. Generally, it is difficult observe luminescence from at room temperature. Furthermore, blue-emitting with quantum efficiency rarely reported. In this study, we succeeded in discovering quantum-efficiency bluish-white-emitting Li
