    测得了Sr1-xBaxNb2O6(SBN)和(K1-yNay)z(Sr1-xBax)l-zNb2O6(KNSBN)晶体的Raman谱,并用群论和晶格动力学观点进行了讨论.为其掺杂改性提供了科学依据.

     

    Abstract

    The Raman spectra of Sr1-xBaxNb2O6(SBN) and (K1-yNay)z(Sr1-xBax)l-zNb2O6(KNSBN) crystals have been obtained and discussed based on the space group theory and lattice dynamics. It provides scientific basic for an improvement on SBN and KNSBN by ion doping.
