Photochromic ceramic as well as preparation method and application thereof
The invention provides photochromic ceramic as well as a preparation method and application thereof. The chemical composition formula of the photochromic ceramic is La2MgSnO6: x% Er and y% Fe, x is equal to 0.5-5, and y is equal to 0.13-3. The photochromic ceramic shows brown under the excitation of light with the wavelength of 275 nm, shows white under the excitation of light with the wavelength of 365 nm, and shows brown-white-brown continuous repeatable color change under the alternate excitation of the light with the wavelength of 275 nm and the light with the wavelength of 365 nm. Green up-conversion luminescence and green down-conversion luminescence are generated under excitation of light with the wavelength of 980 nm and light with the wavelength of 365 nm, luminescence can be statically and dynamically regulated and controlled through the color changing characteristic, and information safety is protected. The invention also provides a preparation method and application of the photochromic ceramic.
本发明提供了一种光致变色陶瓷及其制备方法和应用。本发明的光致变色陶瓷，化学组成式为La2MgSnO6:x％Er，y％Fe，其中x＝0.5～5，y＝0.13～3。该光致变色陶瓷在275nm波长光激发下显现出棕色，在365nm波长光激发下显现出白色，在275nm波长光与365nm波长光交替激发下显现出棕色‑白色‑棕色连续可重复的颜色变化。在980nm波长光与365nm波长光激发下产生绿色上转化发光与绿色下转换发光，且通过变色特性能分别静态与动态地调控其发光，利于保护信息安全。本发明还提供了光致变色陶瓷的制备方法和应用。
