The binary system Sb-Se was studied via laser ablation using antimony-selenium mixtures made from powdered elements in various ratios generating new Sb{sub m}Se{sub n} clusters. The results show that in addition to Sb{sub m}{sup +} (m = 1–8) and Se{sub n}{sup +} (n = 2–9) clusters, a series of Sb{sub m}Se{sub n}{sup +} clusters such as SbSe{sub 1–8}{sup +}, Sb{sub 2}Se{sub 1–6}{sup +}, Sb{sub 3}Se{sub 1–5}{sup +}, Sb{sub 4}Se{sub 1–3}{sup +}, and Sb{sub 5}Se{sub 1,2}{sup +} is generated. In addition, some low intensity oxidized clusters like Se{sub 6}O{sub 2}{sup +}, Se{sub 7}O{sub 2}{sup +}, and SbSe{sub 2-6}O{sub 5}{sup +} and partially hydroxylated clusters (SbSeO{sub 2}H{sub 7}{sup +}, SbSe{sub 5}O{sub 4}H{sup +}) are also formed. In total, 24 new antimony selenide clusters were generated. The knowledge gained can contribute to the elucidation of the structure of Sb{sub m}Se{sub n} glasses. .
