Background The photochromic material is a material whose color is reversibly changed under the stimulation of external light. Photochromic phenomena have been widely developed due to their remarkable color change and reversible optical response, particularly inorganic photochromic luminescent materials having higher thermal stability, chemical resistance, fatigue resistance and mechanical strength. Unfortunately, most materials exhibit a broad visible absorption from the F-center, which makes the photochromic color relatively simple and single, often ranging from pale white to gray. Despite some progress in designing polychromatic photochromism, selecting an appropriate matrix crystal structure or striving to stabilize the defect distribution remains a significant challenge. And the traditional organic and inorganic photochromic materials are easy to decompose at high temperature, so that the material structure is irreversibly damaged, and the stability is poor. Zirconia ceramics, as a novel ceramic material, possess many excellent physicochemical properties. The zirconia material has excellent photoelectric performance, high thermal expansion coefficient and refractive index, low thermal conductivity coefficient and friction coefficient, excellent chemical stability, corrosion resistance and erosion resistance, and thus becomes a hot spot in the fields of scientific research and production application. The multi-color photochromic ceramic material which is not easy to be decomposed at high temperature, is not easy to damage in structure, has good chemical stability and excellent optical performance is obtained based on zirconia ceramic, and is beneficial to the technical application and development of the photochromic material.
