Abstract: The present invention relates to a method for producing europium activated yttrium gadolinium borate phosphors and a product produced by the method. The chemical formula of said phosphors is (Y1-x-y-zEuxGdyMz)BO3, wherein: 0.01?x?0.01, 0?y?0.5, M=Ca, Sr, Ba or Mg, 0?z?0.1. The method comprises: mixing a yttrium source, an europium source, a gadolinium source, a boron source and an M source to produce an aqueous solution in a microwave system; placing the aqueous solution into a microwave system, and making the solution reacting under the condition of condensation cycling and stirring to produce a sol; heating the sol in a microwave system to produce a gel; drying, baking, washing and collecting the gel to produce the product. The method of the present invention can greatly short the production period and improve the production efficiency. The europium activated yttrium gadolinium borate phosphor particles is of a particle size as fine as 80 nm and has good uniformity and emitting performance.
