摘要： The lead-free glass composition contains vanadium oxide, tellurium oxide, alkali metal oxide, iron oxide, barium oxide, and tungsten oxide while containing substantially no phosphorus oxide, and further contains at least one of additional components including yttrium oxide, lanthanum oxide, cerium oxide, erbium oxide, ytterbium oxide, aluminum oxide, and gallium oxide. A content of the tellurium oxide is equal to or more than 25 mol %, and equal to or less than 43 mol % in terms of oxide TeO2. A content of the alkali metal oxide is equal to or more than 4 mol %, and equal to or less than 27 mol % in terms of oxide R2O (R: alkali metal element).
