Disclosed is an inorganic-organic hybrid core-shell nanorod () and a light valve having the nanorod (). The nanorod () 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 TiO. 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.

Provided herein is a modified Polyhedral Oligomeric Silsesquioxane (POSS) compound and a light valve device using the modified POSS compound. The modified POSS compound is a liquid compound synthesized via hydroxyl condensation among a component I, a component II and a component III; wherein the component I is a POSS monomer having at least one hydroxyl; the component II is a dihydroxyl-terminated crosslinkable monomer or oligomer; the component III is a dihydroxyl-terminated non-crosslinkable monomer or oligomer. The light valve device being capable of electronically changing its light transmittance is made by sandwiching a light control layer between two transparent electroconductive substrate layers. The light control layer is made by a solid polymeric matrix containing modified POSS compound. The solid polymeric matrix is formed by solidifying of a modified POSS compound under ultraviolet irradiation or heating.
