MULTICHROIC GLASSES WITH PRASEODYMIUM AND NEODYMIUM

摘要

A glass that includes Pr₂O₃ and Nd₂O₃ such that the sum of Pr₂O₃ and Nd₂O₃ is greater than 0.2 mole% and the ratio of Nd₂O₃ to Pr₂O₃ is greater than 0.5 and less than 3. Further, the sum of any chromophores in the glass from the group V₂O₅, Cr₂O₃, MnO, Mn₂O₃, Fe₂O₃, CoO, C0₃O₄, CuO, NiO, Nb₂O₅, CeO₂, Ho₂O₃ and Er₂O₃ is less than 0.1 mole%. The glass can be characterized by a substantially pink color upon exposure to an incandescent light source and a substantially green color upon exposure to a fluorescent light source. The glass can optionally include one or more fluorescent ions selected from oxides of Cu, Sn, Mn, Ag, Sb, Ce, Sm, Eu, Tb, Dy, Tm, and combinations thereof, such that a total concentration of fluorescent ions is from greater than or equal to about 0.01 mole% to less than or equal to about 5.0 mole%.
