    • 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 SiO2; 2 to 75% by weight of B2O3; not more than 10% by weight of Al2O3; 2 to 30% by weight of at least one member selected from the group consisting of Li2O, Na2O, K2O, Rb2O and Cs2O; 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, Nb2O5, ZrO2, La2O3, Y2O3, Ta2O3 and Gd2O3; not more than 5% by weight of at least one member selected from the group consisting of Sb2O3 and As2O3; not more than 5% by weight of SnO2; 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.
    • 本发明提供一种含有能够令人满意地透过波长为450nm〜600nm的光的卤化铜(I)微粒的蓝紫色遮光玻璃,并且能够清除波长短于450nm的光。 具体地说,本发明提供了含有卤化铜(I)和银的蓝紫色遮光玻璃; 例如,20〜85重量%的SiO 2; 2〜75重量%的B2O3; 不大于10重量%的Al 2 O 3; 2至30重量%的选自Li 2 O,Na 2 O,K 2 O,R b O 2和C 8 O 2中的至少一种; 1至15重量%的选自MgO,CaO,SrO,BaO和ZnO中的至少一种; 不大于10重量%的选自PbO,Nb 2 O 5,ZrO 2,La 2 O 3,Y 2 O 3,Ta 2 O 3和Gd 2 O 3中的至少一种; 不大于5重量%的选自Sb 2 O 3和As 2 O 3中的至少一种; 不超过5重量%的SnO 2; 0.01至10重量%的卤化铜(I); 和0.001〜1重量%的以金属计算的银。
