摘要：
The infrared and Raman spectra of the Nasicon-type chromium systems are found to be very sensitive to the composition and to the nature of the metallic ions. The frequency shift of the infrared active modes involving the metallic ions is correlated to the modification of the crystal field around these ions. The static short-range disorder, particularly characterized from the Raman spectra, is essentially interpreted in terms of Na+ ion site occupation change vs the composition and the temperature. © 1992.
