Fig. 4: Emission spectra of PiSG embedded with various phosphors.
From: Highly efficient phosphor-glass composites by pressureless sintering

The emission color of these PiSG composites can cover the whole visible range when doped with different phosphors. Photos of PiSG samples under the 365 nm (for BAM:Eu) or 450 nm (for others) excitation and their IQE values are both shown on the right.
