Leiming Wu, Taojian Fan, Songrui Wei, Yijun Xu, Ye Zhang, Dingtao Ma, Yiqing Shu, Yuanjiang Xiang, Jun Liu, Jianqing Li, Krassimir Panajotov, Yuwen Qin, and Han Zhang
The Kerr nonlinearity in two-dimensional (2D) nanomaterials is emerging as an appealing and intriguing research area due to their prominent light processing, modulation, and manipulation abilities. In this contribution, 2D black arsenic-phosphorus (B-AsP) nanosheets (NSs) were applied in nonlinear photonic devices base

Highly efficient emission and high-CRI warm white light-emitting diodes from ligand-modified CsPbBr3 quantum dots
Dongdong Yan, Shuangyi Zhao, Yubo Zhang, Huaxin Wang, and Zhigang Zang
All-inorganic CsPbBr3 perovskite quantum dots (QDs) have received great attention in white light emission because of their outstanding properties. However, their practical application is hindered by poor stability. Herein, we propose a simple strategy to synthesize excellent stability and efficient emission of CsPbBr3

Dynamic phase assembled terahertz metalens for reversible conversion between linear polarization and arbitrary circular polarization
Jitao Li, Guocui Wang, Zhen Yue, Jingyu Liu, Jie Li, Chenglong Zheng, Yating Zhang, Yan Zhang, and Jianquan Yao
If a metalens integrates the circular polarization (CP) conversion function, the focusing lens together with circular-polarizing lens (CPL) in traditional cameras may be replaced by a metalens. However, in terahertz (THz) band, the reported metalenses still do not obtain the perfect and strict single-handed CP, because
