Example embodiments relate to extreme ultraviolet absorbing alloys. One example embodiment includes an alloy. The alloy includes one or more first elements selected from: a first list consisting of: Ag, Ni, Co, and Fe; and a second list consisting of: Ru, Rh, Pd, Os, Ir, and Pt. The alloy also includes one or more second elements selected from: the first list, if the one or more first elements are not selected from the first list; and a third list consisting of Sb and Te. An atomic ratio between the one or more first elements and the one or more second elements is between 1:1 and 1:5 if the one or more second elements are selected from the third list and between 1:1 and 1:19 if the one or more second elements are not selected from the third list.
