High-color-rendering fluorescent ceramic having flat-concave structure film and used for laser illumination, and preparation method thereof
The invention discloses a high-color-rendering fluorescent ceramic having a flat-concave structure film and used for laser illumination, and a preparation method thereof. The high-color-rendering fluorescent ceramic comprises a ceramic body, wherein the chemical composition of the ceramic body is (CexY1-x)3Al5O12, x is more than or equal to 0.001 and less than or equal to 0.03, and flat-convex protrusions are arranged on the top surface of the ceramic body; and a film layer body, wherein the top surface of the ceramic body is covered with the film layer body, the bottom surface of the film layer body is provided with flat-concave recesses corresponding to the flat-convex protrusions, the flat-concave recesses are matched with the flat-convex protrusions, and red fluorescent powder is distributed in the film layer body. According to the invention, the problem of non-uniform light spot color caused by non-uniform spatial distribution of blue light in an illumination product can be effectively solved, and the problems of high color temperature, low color rendering and the like caused by insufficient red light components of a YAG:Ce fluorescent material can be improved by the red fluorescent powder doped with the film.
本发明公开具有平凹形结构薄膜的高显色性激光照明用荧光陶瓷及其制备方法，包含有，包含有，陶瓷本体，其化学组成为：(CexY1‑x)3Al5O12，其中，x的取值范围为：0.001≤x≤0.03，所述陶瓷本体的顶面上布置有平凸形隆起部；以及，薄膜层体，其覆盖于所述陶瓷本体的顶面，所述薄膜层体的底面上布置有与所述平凸形隆起部对应的平凹形凹陷部，所述平凹形凹陷部与所述平凸形隆起部相配合，并且，所述薄膜层体的内部分布有红色的荧光粉体。本发明的有益效果在于：能够有效地解决照明产品中由于蓝光空间分布不均匀导致光斑颜色不均匀的问题，薄膜掺杂的红色荧光粉能够改善使用YAG：Ce荧光材料红光成分不足导致的色温高显色性低等问题。
