Abstract:
The present invention provides a light valve containing ABX 3  perovskite particles; more specifically is related to a light valve containing halide ABX 3  perovskite particles that can control light transmittance. The preferable halide ABX 3  perovskite particles in this invention consist of A being at least one of Cs + , CH3NH3 + , and Rb + , B being at least one of Pb 2+ , Ge 2+ , and Sn 2+ , and X being at least one of Cl − , Br − , and I − . This kind of halide ABX 3  perovskite particles were suspended in a liquid suspension to make a light valve with a light transmittance control, which discloses a completely new application for ABX 3  perovskite materials.

Claim (Index 1):
A light valve, comprising a first layer of a transparent conductive substrate, an active layer containing ABX 3  perovskite particles, and a second layer of transparent conductive substrate, wherein said ABX 3  perovskite particles have a non-spherical morphology and are in a liquid suspension, and wherein A is at least one of Cs + , CH 3 NH 3 + , and Rb + ; B is at least one of Pb 2+ , Ge 2+ , and Sn 2+ ; and X is at least one of Cl \u2212 , Br \u2212 , and I \u2212 ; wherein said ABX 3  perovskite particles morphology is nanorods having an average length of about 200 nm-500 nm, and an average diameter of 50 nm-100 nm.
