Abstract
A glass having from greater than or equal to about 0.1 mol. % to less than or equal to about 20 mol. % Ho2O3, and one or more chromophores selected from V, Cr, Mn, Fe, Co, Ni, Se, Pr, Nd, Er, Yb, and combinations thereof. The amount of Ho2O3 (mol. %) is greater than or equal to 0.7(CeO2 (mol. %)+Pr2O3 (mol. %)+Er2O3 (mol. %)). The glass can include one or more fluorescent ions selected from Cu, Sn, Ce, Eu, Tb, Tm, and combinations thereof in addition to, or in place of the chromophores. The glass can also include multiple fluorescent ions.
