Hybrid　copper(I)　halides　have　garnered　a　significant　amount　of　attention　as　potential　substitutes　in　luminescence　and　scintillation　applications.　Herein,　we　report　the　discovery　and　crystal　growth　of　new　zero-dimensional　compounds,　(C2H8N)(3)Cu2I5　and　(C2H8N)(4)Cu2Br6.　The　bromide　and　iodide　have　a　triclinic　structure　with　space　group　P1　and　an　orthorhombic　structure　with　space　group　Pnma,　respectively.　(C2H8N)(3)Cu2I5　exhibits　cyan　emission　peaking　at　504　nm　with　a　photoluminescence　quantum　yield　(PLQY)　of　34.79%,　while　(C2H8N)(4)Cu2Br6　shows　yellowish-green　emission　peaking　at　537　nm　with　a　PLQY　of　38.45%.　The　temperature-dependent　photoluminescence　data　of　both　compounds　were　fitted　to　theoretical　models,　revealing　that　nonradiative　intermediate　states　significantly　affect　thermal　quenching　and　antiquenching.　Electron-phonon　interactions,　the　origin　of　emission　line　width　broadening　and　peak　shifting,　were　also　investigated　via　fittings.　The　scintillation　properties　of　(C2H8N)(3)Cu2I5　were　evaluated,　and　an　X-ray　imaging　device　was　successfully　fabricated　using　(C2H8N)(3)Cu2I5.　This　work　demonstrates　the　potentiality　of　copper　halides　in　lighting　and　X-ray　imaging　applications.
