Fluorescent ceramic, preparation method thereof and luminescent device
The invention provides fluorescent ceramic, a preparation method thereof and a luminescent device. The fluorescent ceramic comprises a fluorescent ceramic substrate, the fluorescent ceramic substrate is provided with a light-in surface, a light-out surface and a side surface, the light-in surface and the light-out surface are oppositely arranged, the side surface is located between the light-in surface and the light-out surface, and the light-out surface and at least part of the side surface are provided with corrosion texture structures formed through corrosion. The light is greatly scattered under the action of the corrosion texture structures on the light-emitting surface and the side surface, and is finally compounded to form more homogeneous white light to be emitted, so that the problem of'yellow edge effect 'can be obviously improved.
本申请提供了一种荧光陶瓷及其制备方法、发光器件。该荧光陶瓷包括荧光陶瓷基片，所述荧光陶瓷基片具有入光面、出光面和侧面，所述入光面和所述出光面相对设置，所述侧面位于所述入光面和所述出光面之间，所述出光面和至少部分所述侧面上均具有经腐蚀形成的腐蚀纹理结构。光线在在出光面和侧面上的腐蚀纹理结构的作用下发生大量散射，并最终复合形成更为均质的白光出射，从而能够明显改善“黄边效应”的问题。
