A triangular lattice selenide series of rare earths (RE), CsRESe2, were synthesized as large single crystals, using a flux growth method. This series stabilized in either trigonal (R$$\overline{3m}$$) or hexagonal (P63/mmc) crystal systems. Physical properties of CsRESe2 were explored by magnetic susceptibility and heat capacity measurements down to 0.4 K. Antiferromagnetic interaction was observed in all magnetic compounds, while no long-range magnetic order was found, indicating the frustrated magnetism. CsDySe2 presents spin freezing at 0.7 K, revealing a spin-glass state. CsCeSe2 and CsYbSe2 present broad peaks at 0.7 and 1.5 K, respectively, in the magnetization, suggesting the short-range interactions between magnetic RE ions. Furthermore, the lack of signature for long-range magnetic order and spin freezing down to 0.4 K in these compounds (RE = Ce, Yb) implies their candidacy for a quantum spin liquid state.
