چکیده انگلیسی
Results of dielectric, spectral and Raman scattering studies of SrTiO3:Nd are reported in the paper, and are compared with one for nominally pure crystal. Dielectric and Raman investigations were conducted at the temperature range from 25 K to room temperature. Analysis of dielectric susceptibility T-dependence for test frequency of 1 MHz was conducted. Raman spectra contain broad peak with drastic anomalies at T-dependence of intensity around 105 K, indicating the existence of a phase transition (PT). The band gap studies were conducted by analyzing UV–vis spectroscopy. The transmission spectra at 300 K show a linear fit for direct transition.
