A systematic study of rare‐earth ions size‐dependent structural phase transition from monazite to zircon‐type in rare earth chromates using Raman spectroscopy
Abstract:Rare earth chromates (RCrO 4 ) undergo monazite to zircon-type structural phase transition due to a decreased rare-earth ion size. They also exhibit an intermediate mixed phase. However, there is no systematic study on the influence of structural distortion on their phononic behavior, which is quite sensitive to subtle environmental variations. A change in the room temperature phononic spectrum was studied in the family of RCrO 4 compounds, where R was varied from La to Yb using Raman modes. With an increase i… Show more
