摘要:
The invention relates to a conversion material, in particular for a white or colored light source comprising a semiconductor light source as primary light source, comprising a matrix glass that, as bulk material, for a thickness d of about 1 mm, has a pure transmission τi of greater than 80% in the wavelength region from 350 to 800 nm and in the region in which the primary light source emits light, wherein the sum of transmission and reflection of the sintered matrix glass without luminophore is at least greater than 80% in the spectral region from 350 nm to 800 nm and in the spectral region in which the primary light source emits light.

Zirconium-containing BaO- and PbO-free X-ray opaque glasses having a refractive index nd of about 1.57 to about 1.61 and a high X-ray opacity with an aluminum equivalent thickness of at least about 400% are provided. Such glasses are based on a SiO2—Al2O3—La2O3—ZrO2—Cs2O system with additions of Li2O, Na2O, ZnO and/or Ta2O5. Such glasses may be used, in particular, as dental glasses or as optical glasses.
摘要:
The X-ray-opaque glass, which is free of BaO and PbO except for at most impurities, has a refractive index nd of from 1.50 to 1.58 and a high X-ray opacity with an aluminium equivalent thickness of at least 300%. The glass is based on a SiO2—Al2O3—SrO—R2O system with additions of La2O3 and ZrO2. The glass has very good chemical resistance and can be used, in particular, as a dental glass or as an optical glass.
