    Abstract: A preparation method of rare earth ions doped alkali metal silicate luminescent glass is provided. The steps involves: step 1, mixing the source compounds of cerium, terbium and alkali metals and putting the mixture into solvent to get a mixed solution; step 2, impregnating the nanometer micropores glass with the mixed solution obtained in step 1; step 3: calcining the impregnated nanometer micropores glass obtained in step 2 in a reducing atmosphere, cooling to room temperature, then obtaining the cerium and terbium co-doped alkali metal silicate luminescent glass. Besides, the rare earth ions doped alkali metal silicate luminescent glass prepared with aforesaid method is also provided. In the prepared luminescent glass, cerium ions can transmit absorbed energy to terbium ions under the excitation of UV light due to the co-doping of cerium ions. As a result, the said luminescent glass has higher luminous intensity than the glass only doped with terbium.

    Abstract: Fused silica glass having an internal transmittance of UV with 245 nm wavelength, being at least 95% at 10 mm thickness, a OH content of not larger than 5 ppm, and a content of Li, Na, K, Mg, Ca and Cu each being smaller than 0.1 ppm. Preferably the glass has a viscosity coefficient at 1215° C. of at least 1011.5 Pa·s; and a Cu ion diffusion coefficient of not larger than 1×10−10 cm2/sec in a depth range of greater than 20 μm up to 100 μm, from the surface, when leaving to stand at 1050° C. in air for 24 hours. The glass is made by crystobalitizing powdery silica raw material; then, fusing the crystobalitized silica material in a non-reducing atmosphere. The glass exhibits a high transmittance of ultraviolet, visible and infrared rays, has high purity and heat resistance, and exhibits a reduced diffusion rate of metal impurities, therefore, it is suitable for various optical goods, semiconductor-production apparatus members, and liquid crystal display production apparatus members.

    Abstract: An improved sol-gel process is disclosed for the making of large synthetic silica based bioactive materials objects crack-free. A series of ordered mesoporous SiO2—CaO—P2O5 sol-gel glasses which are highly bioactive are synthesized through a sol-gel process. The mesoporous glasses are highly bioactive compared with conventional ones, due to the increased textural characteristics, i.e. surface area. The bioactivity tests point out that the surface area, porosity, and 3D-structure become more important than chemical composition during the apatite crystallization stage in these materials, due to the very high textural parameters obtained. The product is intended to be used for tissue engineering applications.
