Document Type and Number:
Japanese Patent JP7142576
Kind Code:
B2
Abstract:
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, Co3O4, 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 %.
