摘要： A light valve containing ABX3 perovskite particles (200) suspended in a liquid suspension (300) that can control light transmittance is provided. The preferable ABX3 perovskite particles (200) are halide ABX3 perovskite particles wherein A is at least one of Cs+, CH3NH3+, and Rb+, B is at least one of Pb2+, Ge2+, and Sn2+, and X is at least one of Cl−, Br−, and I−. Use of the light valve in the manufacture of a light control device and a method of controlling light transmittance by using the light valve are also provided.

摘要： Disclosed is an inorganic-organic hybrid core-shell nanorod (200) and a light valve having the nanorod (200). The nanorod (200) comprises a nanorod inner core composed of a metal oxide and a nanorod shell composed of an inorganic-organic complex containing carbon and nitrogen atoms. The nanorod inner core is titanium dioxide TiO2. The core-shell nanorod employs the metal oxide as a core body and the inorganic-organic complex as a shell to account for the many advantages of inorganic-organic hybrid materials, nanomaterials, and the core-shell structure. The synergistic effect of multiple characteristics allows the material to have unique properties. The light valve made of the material has excellent performance, can adjust the light transmittance in a wider range, and has excellent application prospects.

摘要： A reverse mode light valve, the manufacture of a light control device and a method of controlling light transmittance by using of the reverse mode light valve, the reverse mode light valve containing ABX3 perovskite particles (200) suspended in a liquid suspension (300) can control light transmittance in a higher light transmittance when the power is turned off (OFF state) and lower light transmittance when the power is turned on (ON state). In the ABX3 perovskite particles (200), A is at least one of Cs+, CH3NH3+, and Rb+, B is at least one of Pb2+, Ge2+, and Sn2+, and X is at least one of Cl−, Br−, and I−.
