In　recent　years，　organic⁃inorganic　hybrid　metal　halide　materials　have　attracted　great　attention　due　to　their　excellent　luminescent　properties.　In　particular，　low-dimensional　copper（Ⅰ）　based　halides，　as　a　representative　of　highly　efficient　luminescent　materials，　show　great　potential　in　scintillators　for　radiation　detection.　In　this　paper，　the　research　of　organic⁃inorganic　hybrid　copper（Ⅰ）　based　halides　as　luminescent　materials　is　reviewed.　Based　on　the　［CuXn］（X=Cl，　Br，　I）　structural　unit　and　its　connection　modes，　ionic　organic⁃inorganic　hybrid　copper（Ⅰ）　based　halides　are　systematically　classified，　and　the　relationship　between　their　composition，　structure，　and　properties　is　discussed.　We　focus　on　the　photophysical　process　and　luminescence　mechanism　of　organic-inorganic　hybrid　copper（Ⅰ）　based　halides.　Finally，　we　summarize　the　latest　progress　in　organic⁃inorganic　hybrid　copper（Ⅰ）　based　halide　scintillators　for　X-ray　detection，　and　make　a　prospect　for　this　novel　research　perspective.　©　2023　Chines　Academy　of　Sciences.　All　rights　reserved.
