ABSTRACT
This work presents a pressure-dependent behavior of silver trimolybdate dihydrate (Ag2Mo3O10·2H2O) nanorods using in situ Raman scattering. The Ag2Mo3O10·2H2O nanorods were obtained by the hydrothermal method at 140 °C for 6 h. The structural and morphological characterization of the sample was performed by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). Pressure-dependent Raman scattering studies were performed on Ag2Mo3O10·2H2O nanorods up to 5.0 GPa using a membrane diamond-anvil cell (MDAC). The vibrational spectra under high pressure showed splitting and emergence of new bands above 0.5 GPa and 2.9 GPa. Reversible phase transformations under pressure were observed in silver trimolybdate dihydrate nanorods Phase I - ambient phase (1 atm - 0.5 GPa) â Phase II (0.8 GPa - 2.9 GPa) â Phase III (above 3.4 GPa).
