The authors study the rare earth titanates obtained by quenching from the melt using Raman spectroscopy. Secimens with the general formula Ln/sub 2/Ti/sub 2/O/sub 7/ and Ln/sub 2/TiO/sub 5/ (Ln = La to Lu, Y) were prepared by melting the initial oxides on a Uran beam-heating unit, followed by quenching on a cooled substrate. The Raman spectra were excited by an argon laser and recorded by means of a double monochromator in the photon counting regime. With an increase in the rate of quenching the structure was altered for certain specimens, this being established from the x-ray diffraction patterns and the Raman spectra.
