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.

Abstract: An environmental-friendly and solvent-based inkjet ink composition particularly well suited for use in an inkjet printer is provided. The inkjet ink composition includes a food-grade solvent that has a relatively high polarity, a dye or a pigment, a resin, a surfactant, a homogenizer, an emulsifier, a wetting agent, and an UV absorber. More specifically, a biodegradable food-grade solvent that has relatively high polarityc, a low-volatile and low-toxic polypropylene glycol monoalkyl ether homogenizer, a low-toxic glycol ether emulsifier, a high-boiling polyethylene glycol ether solvent, a fruit-smelling acetoacetate solvent, a food-grade scratch-resistant PVC resin, a weather-resistant acrylic resin, an UV absorber, and a non-harmful surfactant containing silicon or not containing silicon are used in the inkjet ink composition of the present invention.
