摘要
The Ca4Nb2O9–xNd2O3 (where x = 0.1–1.0) pseudobinary samples were synthesized by the high-temperature solid state method. Optical properties of Nd3+ ions in this oxide system were studied and related to the structural phase transition dependent on the Nd2O3 oxide content. Structural and optical properties are discussed based on ATR IR, dielectric, diffuse reflectance and emission spectra measurements. The spectroscopic studies show a structural phase transition occurring for x = 0.5 and for which the initial limited solid solution transforms to the diphasic form of Ca2NdNbO6 and Nd2O3.
