Photochromic ceramic as well as preparation method and application thereof
The invention relates to the technical field of anti-counterfeiting ceramic materials, in particular to photochromic ceramic as well as a preparation method and application thereof. The invention relates to a photochromic ceramic, which comprises a ceramic material with a chemical composition of Ba3MgSi2O8. The photochromic ceramic disclosed by the invention can realize triple dynamic anti-counterfeiting of color change, luminous intensity change and luminous color change of a ceramic sample, and provides an additional means for anti-counterfeiting identification; and the problems of inaccurate identification result and the like caused by the influence of the brightness of the surrounding environment in the process of identifying the anti-counterfeiting only through the light intensity change are solved. In addition, the photochromic ceramic disclosed by the invention is non-rare earth ion energy level transition luminescence, so that the cost is reduced.
本发明涉及防伪陶瓷材料技术领域，尤其是涉及一种光致变色陶瓷及其制备方法和应用。一种光致变色陶瓷，包括化学组成为Ba3MgSi2O8陶瓷材料。本发明的光致变色陶瓷能够实现陶瓷样品颜色变化、发光强度变化和发光颜色变化三重动态防伪，为防伪的鉴别提供额外的手段，避免了仅通过发光强弱变化鉴别防伪的过程中容易受到周围环境明暗的影响所造成的鉴别结果不准确等问题。并且，本发明的光致变色陶瓷为非稀土离子能级跃迁发光，降低了成本。
