| 1 | Hybridisation 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 | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 2 | Growth of nitrogen-doped p-type ZnO thin films prepared by atomic layer epitaxy显示文摘Nitrogen-doped, p-type ZnO thin films were grown successfully on sapphire (0001) substrates by using atomic layer epitaxy (ALE). Zn(C2H5)2 [Diethylzinc, DEZn], H2O and NH3 were used as a zinc precursor, an oxidant and a doping source gas, respectively. The lowest electrical resistivity of the p-type ZnO films grown by ALE and annealed at 1000 ℃ in an oxygen atmosphere for 1 h was 18.3 Ω·cm with a hole concentration of 3.71×1017 cm-3. Low temperature-photoluminescence analysis and time-dependent Hall measurement results support that the nitrogen-doped ZnO after annealing is a p-type semiconductor. | LEE Chongmu LIM Jongmin PARK Suyoung KIM Hyounwoo | 2006 | Rare Metals2006，25，z1： | 2 |

| 4 | Highly ordered lead-free double perovskite halides by design显示文摘Lead-free double perovskite halides are emerging optoelectronic materials that are alternatives to leadbased perovskite halides.Recently,single-crystalline double perovskite halides were synthesized,and their intriguing functional properties were demonstrated.Despite such pioneering works,lead-free double perovskite halides with better crystallinity are still in demand for applications to novel optoelectronic devices.Here,we realized highly crystalline Cs2AgBiBr6 single crystals with a well-defined atomic ordering on the microscopic scale.We avoided the formation of Ag vacancies and the subsequent secondary Cs3Bi2Br9 by manipulating the initial chemical environments in hydrothermal synthesis.The suppression of Ag vacancies allows us to reduce the trap density in the as-grown crystals and to enhance the carrier mobility further.Our design strategy is applicable for fabricating other lead-free halide materials with high crystallinity. | Chang Won Ahn Jae Hun Jo Jong Chan Kim Hamid Ullah Sangkyun Ryu Younghun Hwang Jin San Choi Jongmin Lee Sanghan Lee Hyoungjeen Jeen Young-Han Shin Hu Young Jeong Ill Won Kim Tae Heon Kim | 2020 | Journal of Materiomics2020，6，4： | 2 |
