(KSF) red phosphor was prepared
via
a low-temperature co-sintering method. The results show that the thermal erosion effect of the precursor glass melt on KSF phosphor is limited during co-sintering
so the optical properties of the phosphor are retained. Compared with the initial phosphor
the thermal quenching properties of glass ceramics are greatly improved. The fabricated laser lighting source exhibits lumen of 32.77 lm

KSF fluorescent glass ceramic is expected to be applied in the field of high power indoor lighting.
