稀土元素的荧光性质早在1909年就已被发现,但是较广泛的应用是从60年代开始的。现在稀土荧光材料已经成为单一高纯稀土氧化物应用的主要领域。下面列举几种常 The fluorescence properties of rare earth elements have been discovered as early as 1909, but the more widespread use began in the 1960s. Now rare-earth fluorescent materials have become the main areas of application of a single high purity rare earth oxide. Here are some common
