1Hybridisation of perovskite nanocrystals with organic molecules for highly efficient liquid scintillators显示文摘Compared with solid scintillators,liquid scintillators have limited capability in dosimetry and radiography due to their relatively low light yields.Here,we report a new generation of highly efficient and low-cost liquid scintillators constructed by surface hybridisation of colloidal metal halide perovskite CsPbA_(3)(A:Cl,Br,I)nanocrystals(NCs)with organic molecules(2,5-diphenyloxazole).The hybrid liquid scintillators,compared to state-of-the-art CsI and Gd_(2)O_(2)S,demonstrate markedly highly competitive radioluminescence quantum yields under X-ray irradiation typically employed in diagnosis and treatment.Experimental and theoretical analyses suggest that the enhanced quantum yield is associated with X-ray photon-induced charge transfer from the organic molecules to the NCs.High-resolution X-ray imaging is demonstrated using a hybrid CsPbBr_(3) NC-based liquid scintillator.The novel X-ray scintillation mechanism in our hybrid scintillators could be extended to enhance the quantum yield of various types of scintillators,enabling low-dose radiation detection in various fields,including fundamental science and imaging.Sangeun Cho Sungwoo Kim Jongmin Kim Yongcheol Jo Ilhwan Ryu Seongsu Hong Jae-Joon Lee SeungNam Cha Eun BiNam Sang Uck Lee Sam Kyu Noh Hyungsang Kim Jungwon Kwak Hyunsik Im 2020Light(Science & Applications)2020,9,1:4
