Method for preparing silicate fluorescent powder for LED

The invention belongs to the technical field of preparing fluorescent powder through the wet chemical method, and particularly relates to a method for preparing silicate fluorescent powder for an LED. Silicate fluorescent powder is prepared through the sol-gel method, and the silicate fluorescent powder can be obtained through low-temperature forging in the later stage. Compared with a traditional high-temperature solid phase method, later forging temperature required by the sol-gel method is low, requirements of equipment is not high, energy consumption is low, and the method is suitable for industrial production. The obtained fluorescent powder is uniform in dispersion and easily achieves energy transmission. The obtained fluorescent powder is uniform in particle size distribution, uniform mixing of the fluorescent powder and glue in later application is facilitated, and the fluorescent powder is suitable for the LED. Market prospects and economic value are large. 本发明属于湿化学法制备荧光粉技术领域，具体涉及种LED用硅酸盐荧光粉的制备方法。采用溶
