858nm激光激发下掺Nd^(3+)氟化物陶瓷体上的转换发光研究

The influence of preparing process to up conversion characteristics of rare earth doped ceramics

本文报道了三种方法制备的掺Nd3+氟化物烧结陶瓷体的上转换发光特性。不同的制备方法可以造成基质中稀土离子分布的不同。在一定条件下基质中可聚合形成合适的稀土离子的团簇 。

In this paper,the influence of different processes to up conversion characteristics of Nd 3+ doped materials has been reported.The difference of processes could cause the difference of the distribution of rare earth ions in the host.Under certain circumstance,rare earth clusters appear in thd host.The formation of rare earth clusters brings about the interaction among rare earth ions in the cluster,which results in the appearance of new up conversion mechanism.The experiment results indicate that Nd 3+ doped in suitable host could possess excellent up conversion performance.
