| titleOfInvention | A kind of gallate ability of reverse photochromism material and preparation method thereof |
| abstract | The present invention provides a kind of gallate ability of reverse photochromism materials, have chemical formula shown in Formulas I: Ca 1‑x Ga 4 O 7 : xM Formulas I；Wherein, x is the doping content of M, 0 < x≤0.04；M is Cr 3+ 、Dy 3+ 、Er 3+ 、Eu 3+ 、Gd 3+ 、Ho 3+ 、Nd 3+ 、Pr 3+ 、Sm 3+ 、Tb 3+ 、Tm 3+ And Yb 3+ One or more of.Photochromic material in the present invention after ultraviolet light its body colour can by it is colourless slowly become it is rose pink, after visible light, sunlight irradiation or high-temperature process, it can be restored to the colourless or light green color of script again, being placed on after saving 3 months in darkroom after material coloring in the present invention still can obviously observe this phenomenon, illustrate that the discoloration persistence of material of the present invention is good, and its thermal stability is high, fatigue resistance is good.The present invention also provides a kind of preparation methods of gallate ability of reverse photochromism material. |
