一种蓝紫光激发的黄光荧光材料及其制备方法和应用
摘要：
本发明公开了一种蓝紫光激发的黄光荧光材料，其化学表达式如下：SrxCa3-1.5n-xAl1-2ySiyMgyO4F:nCe，其中0.005≤n≤0.1，1.6≤x≤3-1.5n，0≤y≤0.4。其制备方法是以Sr3AlO4F为基质，通过掺杂Ce取代Sr造成晶格缺陷作为发光中心，通过Ca取代Sr，Si和Mg取代Al，以改善晶格环境，使得光色改变，激发主峰波段可调，强度提高。本发明的蓝紫光激发黄光发射材料安全无毒、化学性质稳定、易于长期保存、荧光性能稳定；本发明的方法烧结温度低，工艺简单，适合工业化生产，具有广泛的应用前景。
摘要（英）：

The invention discloses a blue and violet light-excited yellow light fluorescent material. The chemical expression of the blue and violet light-excited yellow light fluorescent material is SrxCa3-1.5n-xAl1-2ySiyMgyO4F, wherein n is more than or equal to 0.005 and less than or equal to 0.1; x is more than or equal to 1.6 and less than or equal to 3-1.5n; and y is more than or equal to 0 and less than or equal to 0.4. In a preparation method of the fluorescent material, Sr3AlO4F is taken as a substrate, Ce is doped for replacing Sr for causing a crystal lattice defect serving as a luminous center, Sr is replaced by Ca, and Al is replaced by Si and Mg, so that the crystal lattice environment is improved, the light color is changed, an exciting main peak waveband is adjustable, and the strength is enhanced. The blue and violet light-excited yellow light fluorescent material disclosed by the invention is safe and nontoxic, has stable chemical property and stable fluorescent performance, and is easy to store for a long time; and the method disclosed by the invention has the advantages of low sintering temperature, simple process, suitability for industrial production and wide application prospect.
