摘　　要：YAG(Y3Al5O12)材料已被广泛应用于各个领域。YAG材料的制备一直备受人们的关注,它一般是通过固相反应方法得到的。由于Sol-gel(溶胶-凝胶)法具有合成温度低、物质反应活性高、各组分混合均匀性好、合成粉体的粒径小和分布窄等优点,用Sol-gel法制备YAG材料已引起了人们的重视。本文概述了近几年来采用Sol-gel法用不同原料制备YAG材料(纤维、发光粉和薄膜)以及它们的主要应用,并讨论了采用Sol-gel技术制备YAG纳米晶／玻璃复合材料的新技术。Yttrium aluminum garnet (YAG) materials have been widely used in many fields. The general preparation method of YAG is solid phase reaction at high temperatures. Since the advantages of lower sintering temperature, high reactivity of starting materials, fine powders, sol - gel method has attracted more and more attention. By using this method, many kinds of YAG materials have been prepared. In this paper, the preparation of YAG materials, such as fiber, film and powder by using sol - gel method and their main applications have been summarized. The new prepared method and the prospect of YAG materials have also been discussed.
