Original article
Abstract: Structure of LiNbO3:Zn crystals was shown to be more ordered in concentration range ~ 3,95÷4,54 mol. % ZnO . Rise of dopant concentration to 5,84 mol. % leads to sharp increase of 876 cm-1 Raman band. This band is connected with changes in B-O-B ( B=Nb, Li , Zn ) bridge. Change of ion contribution to this band explains smooth rise in electro-optical coefficients at 3-7,6 mol. % ZnO in LiNbO3 .
Keywords: single crystal, lithium niobate, doping, zinc cations, Raman spectroscopy, full-profile XRD, stretching modes
