Description
Summary:Solid solutions [Ti.sub.1-x][M.sub.x][O.sub.2-x/2] in the anatase and rutile forms were obtained from the precursors [Ti.sub.1-x][M.sub.x][(OC[H.sub.2]C[H.sub.2]O).sub.2-x/2] at T = 450-900[degrees]C. The temperature and concentration dependence of the phase transformation of anatase to rutile in [Ti.sub.1-x][M.sub.x][O.sub.2-x/2] was investigated by Raman spectroscopy. It was shown that the anatase phase is stabilized most effectively by the [Eu.sup.3+] dopant. Key words: Raman spectroscopy, phase transition.
