The invention discloses a photonic crystal which comprises a base body, the base body is composed of one or more of aluminum oxide micro powder, magnesium oxide micro powder, yttrium oxide micro powder, gadolinium oxide micro powder, gallium oxide micro powder and zirconium oxide micro powder, and a base body raw material is prepared through a powder preparation method. The adopted substrate material oxide micro powder can be commercially available commercial powder, and also can be composite oxide micro powder prepared by a sol-gel method and a coprecipitation method. Specifically, the purity of the powder is greater than 99.9%, and the particle size is less than 1.0 micron. The invention relates to the technical field of biophotonic crystals. The refractive index or crystal lattices of the biophotonic crystals are changed through phase transformation generated under strong sunlight, then the color of the biophotonic crystals is changed, the transmittance of light with the specific wavelength is reduced, and the eye protection and health care effects are achieved through the filtering effect of the biophotonic crystals on part of light.
本发明公开了一种光子晶体，包括基体，所述基体采用氧化铝微粉、氧化镁微粉、氧化钇微粉、氧化钆微粉、氧化镓微粉、氧化锆微粉中的一种或多种组成，利用粉末制备法进行制备成基体原料，上述所采用的基体材料氧化物微粉可以是市售商业粉体，也可以是用溶胶‑凝胶法、共沉淀法自行制备的复合氧化物微粉。具体要求粉体的纯度大于99.9％，粒度小于1.0微米。本发明涉及生物光子晶体技术领域。在较强太阳光下发生的相转变来改变生物光子晶体的折射率或晶格,进而带来生物光子晶体颜色的变化,以降低特定波长光线的透过率，利用生物光子晶体对部分光线的滤过作用,起到眼睛防护和保健作用。
