Complex-phase fluorescent ceramic, preparation method thereof and light-emitting device
The invention discloses a complex-phase fluorescent ceramic, a preparation method thereof and a light-emitting device. The mass fraction of fluorescent powder crystal grains in the complex-phase fluorescent ceramic provided by the invention is 70-90%; and the relative density of the multiphase fluorescent ceramic is 99.0%-99.9%. The multiphase fluorescent ceramic has high density under the condition of high fluorescent powder crystal grain content, and the problem of poor binding force between large-particle-size fluorescent powder crystal grains and small-particle-size aluminum oxide crystal grains is effectively solved, so that the multiphase fluorescent ceramic has good mechanical performance and coating performance while having better luminescence performance; and subsequent processing and packaging are facilitated.
本申请公开了一种复相荧光陶瓷及其制备方法、发光装置，本申请提供的复相荧光陶瓷中荧光粉晶粒的质量分数为70％～90％；且复相荧光陶瓷的相对密度为99.0％～99.9％。复相荧光陶瓷在具有高荧光粉晶粒含量的情况下具有较高的致密度，且有效解决了大粒径的荧光粉晶粒与小粒径的氧化铝晶粒之间结合力差的问题，使得复相荧光陶瓷在具有更好发光性能的同时具有良好的机械性能和镀膜性能，有利于后续的加工和封装。
