Abstract
The present invention provides a blue-violet light blocking glass containing copper (I) halide fine particles that satisfactorily transmits light having a wavelength of 450 nm to 600 nm and sharply blocks light having a wavelength shorter than 450 nm. Specifically, the present invention provides a blue-violet light blocking glass containing a copper (I) halide and silver; for example, 20 to 85% by weight of SiO; 2 to 75% by weight of BO; not more than 10% by weight of AlO; 2 to 30% by weight of at least one member selected from the group consisting of LiO, NaO, KO, RbO and CsO; 1 to 15% by weight of at least one member selected from the group consisting of MgO, CaO, SrO, BaO and ZnO; not more than 10% by weight of at least one member selected from the group consisting of PbO, NbO, ZrO, LaO, YO, TaOand GdO; not more than 5% by weight of at least one member selected from the group consisting of SbOand AsO; not more than 5% by weight of SnO; 0.01 to 10% by weight of a copper (I) halide; and 0.001 to 1% by weight of silver calculated on a metal basis.
