High pressure induces a structural transformation in nano-sized Europium sesquioxide (Eu2O3), shifting from a cubic to a monoclinic phase. This transition begins around 2 GPa and is confirmed by Raman spectroscopy and X-ray diffraction (XRD) studies.

Area of Science:

  • Materials Science
  • Solid State Physics
  • Nanotechnology

Background:

  • Nano-sized Europium sesquioxide (Eu2O3) is a material with potential applications in various fields.
  • Understanding its structural behavior under extreme conditions is crucial for its technological utilization.

Purpose of the Study:

  • To investigate the structural properties of nano-sized Europium sesquioxide (Eu2O3) under high pressure.
  • To determine the pressure-induced structural phase transition of Eu2O3.

Main Methods:

  • High-pressure X-ray diffraction (XRD) and Raman spectroscopy were employed.
  • A Mao-Bell type diamond anvil cell (DAC) was used to generate pressures up to 16.4 GPa.

Main Results:

  • Nano-Eu2O3 exhibits a cubic structure at ambient conditions, with a trace of Eu2+ indicating non-stoichiometry.

  • A pressure-induced phase transition from cubic to monoclinic structure was observed.
  • The cubic-to-monoclinic transition onset is around 2 GPa, completing by 8 GPa, evidenced by new peaks in Raman and XRD data.

    • Conclusions:

    • Nano-sized Europium sesquioxide undergoes a significant structural transformation under high pressure.
    • The observed phase transition from cubic to monoclinic structure is a key finding for understanding Eu2O3's high-pressure behavior.
