Reversible Photochromic Properties of Ti2O3(H2O)2(C2O4) ⋅ H2O Material
Source abstract
Abstract
Abstract Potassium titanyl oxalate is used as the titanium source and HCl as growth promoter. Ti2O3(H2O)2(C2O4) ⋅ H2O, with hexagonal prism and spherical polyhedral morphology, has been synthesized by one‐step hydrothermal method at 120 °C for 6∼12 h, and the particle size range is 8–12 μm. Ti2O3(H2O)2(C2O4) ⋅ H2O prepared in this research has excellent reversible photochromic properties. It is a kind of P‐type photochromic compound, which is achromatic or colorless. The equilibrium time of discoloration or fading is 30 min. The photochromic mechanism research shows that the photochromic properties of Ti2O3(H2O)2(C2O4) ⋅ H2O are caused by the continuous reaction of Ti4+, Ti3+ with ecb−, VO++ in unsaturated cationic compounds.
