摘要：

In this work the site location of several M3+ (M = Cr, Nd, Eu, Ho, Er, Tm) dopant ions in LiNbO3 has been investigated by using optical (absorption and site-selective fluorescence) techniques. Experimental results reveal that the regular cation sites, Li+ and Nb5+, are occupied in all cases and can be characterized optically. Additional crystal field sites, for M = Nd and M = Eu, have been detected by site selective spectroscopy. The effects on the M3+ optical spectra of the stoichiometry and the codoping with MgO have been systematically investigated. The appearance of new sites for the M3+ ions, M3+-Mg2+, is ascertained for M = Cr, Nd, Ho, Ho, and Tm.
