Self-activated luminescence of a phosphor has unique advantages such as natural homogeneity, wide wavelength, without rare-earth dopant, easy preparation, etc. However, its luminescence efficiency usually is not satisfied. This work reports several strategies to modify the intrinsic luminescence int...
