Synergetic Effect of the Surfactant and Silica Coating on the Enhanced Emission and Stability of Perovskite Quantum Dots for Anticounterfeiting.
Fei Zhang,Zhifeng Shi,Sen Li,Zhuangzhuang Ma,Ying Li,Lintao Wang,Di Wu,Yongtao Tian,Guotong Du,Xinjian Li,Chongxin Shan,Chongxin Shan +11 more
TL;DR: It is demonstrated that the CsPbBr3/LP/SiO2 QDs composites can act as a smart concealed ink for information encryption and decryption and the anti-counterfeiting effect can be efficiently sustained even though the paper with designable patterns was crudely treated.

All-inorganic Lead Halide Perovskites: A Promising Choice for Photovoltaics and Detectors
TL;DR: In this article, a narrow-bandgap CsPbI3 polycrystalline bulk film solar cell has achieved the highest power conversion efficiency of 18.4%, while a stable CpbBr3 nanocrystal film is a more successful choice in UV-visible and high-energy ray detections.
