Fluorescent powder for luminous cement-based composite material and preparation method thereof
The invention discloses fluorescent powder for a luminous cement-based composite material. The chemical general formula of the fluorescent powder is Ca2La (Gd) NbO6: 0.01 Bi < 3 + >, the preparation method comprises the following steps: by taking calcium salt, lanthanum oxide, gadolinium oxide, niobium oxide and bismuth oxide as raw materials, proportioning according to the molar ratio of the chemical general formula Ca2La (Gd) NbO6: 0.01 Bi < 3 + >, and uniformly grinding in an agate mortar to obtain a mixture; and carrying out high-temperature sintering on the obtained mixture, and naturally cooling to obtain the Ca2La (Gd) NbO6: 0.01 Bi < 3 + > fluorescent material. When the fluorescent powder disclosed by the invention is applied to a cement-based material, luminescence is not influenced by a cement hydration process, and the luminescence property is not influenced by the addition of a mineral admixture. The fluorescent powder is added into the cement-based material through simple mechanical mixing, so that the cement-based material is endowed with luminescent characteristics under the condition that the mechanical property and durability of the cement-based material are not influenced, the luminescent color is in a blue or cyan region, and the luminescent color is adjustable and controllable.
本发明公开了一种用于发光水泥基复合材料的荧光粉，化学通式为Ca2La(Gd)NbO6:0.01Bi3+；以钙盐、镧的氧化物、钆的氧化物、铌的氧化物和铋的氧化物为原料，依照化学通式Ca2La(Gd)NbO6:0.01Bi3+的摩尔比进行配比，在玛瑙研钵中研磨均匀得到混合物；所得混合物进行高温烧结，自然冷却得到Ca2La(Gd)NbO6:0.01Bi3+荧光材料；本发明的荧光粉应用到水泥基材料时，发光不受水泥水化过程的影响，矿物掺合料的添加不影响发光性能。通过简单的机械混合将荧光粉加入到水泥基材料中，在不影响水泥基材料本身力学性能和耐久性的情况下，赋予水泥基材料发光特性，发光颜色在蓝色或青色区域，发光颜色可调控。
