Novel photochromic material and preparation method thereof
The invention discloses a novel photochromic effect material and a preparation method thereof. The chemical formula of the material is Ba < 0.7 > Sr < 0.21-1.5 x > Ho < x > Yb < 0.06 > Nb < 2 > O < 6 >, and x is equal to 0.0, 0.02, 0.04, 0.08, 0.10, 0.12 or 0.14. The preparation method comprises the following steps: taking SrCO3, BaCO3, Yb2O3, Ho2O3 and Nb2O5 as raw materials, mixing and grinding the raw materials in proportion, and further preparing the Ba < 0.7 > Sr < 0.21-1.5 x > HoxYb < 0.06 > Nb2O6 ceramic material by utilizing a simple high-temperature solid-phase reaction method. The invention has the advantage that the material shows obvious color change under the irradiation of near ultraviolet light. Meanwhile, under thermal stimulation, color change can be restored to a state before irradiation. The material can be used in the fields of optical switches, optical storage, safety anti-counterfeiting and the like in the future.
本发明公开一种新型光致变色效应材料及其制备方法。材料的化学式为Ba0.7Sr0.21‑1.5xHoxYb0.06Nb2O6，其中，x＝0.0、0.02、0.04、0.08、0.10、0.12或0.14。制备方法是以SrCO3、BaCO3、Yb2O3、Ho2O3和Nb2O5作为原料，按比例进行混合研磨，进而利用简单高温固相反应法而制备出Ba0.7Sr0.21‑1.5xHoxYb0.06Nb2O6陶瓷材料。本发明优点：在近紫外光辐照下，材料展现明显的变色。同时，在热刺激下，变色可以被复原到辐照前的状态。该材料未来可用于光开关、光学存储、安全防伪等领域。
