Based on an analysis on the chemical bonding energy of a luminescence center and the thermal stability of luminescence emission, we describe a design idea of high performance phosphor materials. It is to incorporate a superhard chemical bond, Si-C, into the host crystals. Two families of phosphor formulations are designed and prepared through high temperature solid state reaction. The structure determination results of the phosphors demonstrated the incorporation of the Si-C bonds in the crystal. The effect of the Si-C bond in the formulations is evident on luminescence and optical spectra. The thermal quenching profiles of the phosphors show enhanced thermal stability of the luminescence emission as the carbon content is increased.
