<p>Disclosed are CuX-containing, Nd 2 O 3 -containing, UV-absorbing and contrast-enhancing glasses and article comprising the same. The glass has improved UV-absorption and color enhancing capabilities compared to glasses described in the prior art. The glass can be used in sunglass lenses and light filters of information displays. Glasses consist essentially of (in weight %): SiO 2 30-65; B 2 O 3 12-25; Al 2 O 3 3-9; ZrO 2 2-8; Li 2 O 0-5; Na 2 O 0-7; K 2 O 0-10; R 2 O 5-20 (where R represents alkali); 0-10 R'O (where R' represents alkaline earth); ZnO + La 2 O 3 + Gd 2 O 3 + Y 2 O 3 + Ta 2 O 3 + Nb 2 O 5 + Hf 2 O 5 + WO 3 + MoO 3 0-5; TiO 2 0-5; CeO 2 0-2; Pr 2 O 3 0-10; Nd 2 O 3 5-15; En 2 O 3 0-10; NiO 0-2; CuO 0,25-1,5; Cl 0-1; Br 0-3; other halogen 0-2; total of halogens 0,3-3; SnO 0,3-4.</p> |
