Raman spectra of KTa₀.₅Nb₀.₅O₃ nanopowder solid solution were obtained at the temperatures from –190°C to 600°C and investigated for the first time. The compound was synthesized by a new technology. Temperature dependences of the intensity, width and frequency of the B₁(TO₂), A₁(TO₁), B₁(TO₃), A₁(TO...
