Abstract
A glass material is provided, which has a composition of M2O—ZnO-M′203—Bi2O3—SiO2, wherein M is Li, Na, K, or a combination thereof, and M′ is B, Al, or a combination thereof. A fluorescent composite material can be composed of the glass material and a phosphor material. The fluorescent composite material may collocate with an excitation light source to provide a light-emitting device.
