| 2 | A new insight into the unique magneto-optical effect of layered perovskite(C_(6)H_(5)C_(2)H_(3)FNH_(3))_(2)MnCl_(4)显示文摘Magnet-optical materials embracing coupled magnetic and photoluminescent properties in single phase are promising in microelectronics and optoelectronic devices.However,the current research mainly focuses on traditional inorganic materials,and there are few reports on molecule materials.Recently,we synthesized an organic–inorganic hybrid complex((C_(6)H_(5)C_(2)H_(3)FNH_(3))_(2)MnCl_(4)(1)with perovskite structure.Physical measurements show that 1 not only behaves as an antiferromagnet with spin canting but also exhibits unusual fluorescent properties.Importantly,under the magnetic field at different temperatures,the luminous intensity of 1 changed,and a red-shift occurred with obviously optical hysteresis.These phenomena directly prove the existence of magneto-optical coupling in 1.More interestingly,the optical hysteresis can be observed in both low and high field,which is unprecedented in other molecular materials.Even in traditional inorganic materials,it can only be observed in strong field.This special function provides the possibility for the application of low energy consumption optoelectronic devices. | Zhao-Bo Hu Long-He Li Yibo Han Jinlei Zhang Jianrong Li Zilu Chen ShuyiWu Yi Zhang Heng-Yun Ye You Song | 2023 | Aggregate2023，4，3： | 0 |
| 3 | Applications of lasers:A promising route toward low-cost fabrication of high-efficiency full-color micro-LED displays显示文摘Micro-light-emitting diodes(micro-LEDs)with outstanding performance are promising candidates for next-generation displays.To achieve the application of high-resolution displays such as meta-displays,virtual reality,and wearable electronics,the size of LEDs must be reduced to the micro-scale.Thus,traditional technology cannot meet the demand during the processing of micro-LEDs.Recently,lasers with short-duration pulses have attracted attention because of their unique advantages during micro-LED processing such as noncontact processing,adjustable energy and speed of the laser beam,no cutting force acting on the devices,high efficiency,and low cost.Herein,we review the techniques and principles of laser-based technologies for micro-LED displays,including chip dicing,geometry shaping,annealing,laserassisted bonding,laser lift-off,defect detection,laser repair,mass transfer,and optimization of quantum dot color conversion films.Moreover,the future prospects and challenges of laser-based techniques for micro-LED displays are discussed. | Shouqiang Lai Shibiao Liu Zilu Li Zhening Zhang Zhong Chen Rong Zhang Hao-Chung Kuo Tingzhu Wu | 2023 | Opto-Electronic Science2023，2，10： | 0 |
