Embodiment 1

[0042] The preparation of embodiment 1 cesium oleate

[0043] Will Cs 2 CO 3 (4.07g) was charged into a 250mL three-neck flask together with octadecene (50mL, ODE) and oleic acid (11.088g), and the mixture was dried at 120°C for 1 hour, then heated to 150°C under Ar until all Cs 2 CO 3 Both react with oleic acid. Since cesium oleate precipitates out of the ODE at room temperature, it must be warmed up to make it soluble before use.

Embodiment 2

[0044] Example 2CsPbI 3 Synthesis of nanorods

[0045] N,N-Dimethylformamide (100mL, DMF) and PbI 2 2.306 (5mmol) into a 250mL flask. 4.654 g (77.5 mmol) of acetic acid and 0.797 g (4.3 mmol) of dodecylamine were added. in PbI 2 After complete dissolution, 5 mL of cesium oleate solution (prepared as described in Example 1) was added. Then, the mixed solution was added to a 5 L flask together with 4200 mL of toluene.

[0046] Then, the reaction solution was centrifuged at 5000G for 1.5 h and the supernatant was discarded to obtain the light-controlled CsPbI 3 .

[0047] Then, the CsPbI 3 Disperse further with 500 mL of toluene, mix well with shaking and sonication (referred to as LCP-Example-2).

Embodiment 3

[0048] Example 3CsPbBr 3 Synthesis of nanorods

[0049] In the same manner as in Example 2, but using 1.835 g of PbBr 2 Instead of 2.306g PbI 2 . Contains CsPbBr 3 The toluene mixture is called LCP-Example-3.

Abstract

A light valve containing ABX 3 perovskite particles (200) suspended in a liquid suspension (300) that can control light transmittance is provided. The preferable ABX 3 perovskite particles (200) are halide ABX 3 perovskite particles wherein A is at least one of Cs +, CH 3NH 3 +, and Rb +, B is at least one of Pb 2+, Ge 2+, and Sn 2+, 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.

Description

[0001] Cross References to Related Applications [0002] This application is required to be filed on July 12, 2018 and is titled "Halide ABX 3 perovskite particles and their application in controlling photo-flux", the disclosure of which is hereby incorporated by reference. technical field [0003] The present invention relates to particles comprising perovskite, in particular ABX 3 Light valves for perovskite particles. The present invention also provides a new use of the light valve and a method of controlling light transmittance by using the light valve. Background technique [0004] Light valves are devices that can electronically control light transmission, and such devices are also scientifically known as electrochromic devices. Technically, like a water valve that controls the flow of water, a light valve is a device that regulates the amount of light passing through a medium. Based on the science behind electrochromic devices, electrochromic devices can be furthe...
