Abstract：In recent years，two-dimensionalrare-earth materials have rapidlybecomeafrontierand hot spotin scientificresearchdueto their uniqueproperties thatcombine thoseof two-dimensional materials andrare-earth materials.To achieve theapplicationof two-dimensional rare-earth materials in the fieldsofoptics，electronics，and magnetism，theirsynthesisisofcrucialimportance.Themethodsforsynthesizing two-dimensionalrare-earthmaterials have beensummarized.Among them，chemicalvapor deposition（CVD） is one of the commonly used methods，and salt-assisted CVD can be used to synthesize binary（such as Gd 205 ， CeO2 ，E 1203 ，etc.）and ternary（such asEuOCl，LaOCl， Er202S ，etc.）two-dimensional rare-earth compounds；mechanical exfoliation is oftenused to synthesize two-dimensionalrare-earth oxyhalidesand telurides；coating methods include molecularbeam epitaxy，thermal deposition，and others，which can be used to synthesize GdSi2， EuGe2 ，SmSe，etc.Finally，the prospect of large-scale synthesis of two-dimensional rare-earth materials have been proposed.
