High-pressure optical study of HfW2O8
Abstract A high-pressure optical absorption study and Raman and infrared spectroscopy are carried out on hafnium tungstate (HfW2O8) at room temperature. The band gap decreases rapidly with pressure until ∼9 GPa is reached, increases between 9 and 16 GPa, and slowly decreases with pressure from 16 to 47 GPa. The changes under pressure of the vibrational modes have been studied, and an estimate o...
متن کاملIn situ high-pressure study of sodium amide by Raman and infrared spectroscopies.
Here we report the first in situ high-pressure study of sodium amide (NaNH(2)) as an agent in potential hydrogen storage applications by using combined Raman and infrared (IR) spectroscopies at room temperature and pressures up to ~16 GPa. Starting with an orthorhombic crystal structure at ambient pressure, sodium amide was found to transform to two new phases upon compression as evidenced by t...
متن کاملInfrared absorption of compressed hydrogen deuteride and calibration of the ruby pressure gauge
The primary subject of this thesis is the study of solid hydrogen deuteride by infrared absorption up to a pressure of 159 GPa and at temperatures ranging from 4 K to 160 K. This work constitutes the first reported infrared study of hydrogen deuteride in the range of ultra-high pressures where phase transitions occur. A phase transition of orientational ordering, previously observed by Raman sc...
متن کاملHigh-pressure stability, transformations, and vibrational dynamics of nitrosonium nitrate from synchrotron infrared and Raman spectroscopy
The properties of nitrosonium nitrate (NONO3 ) were investigated following synthesis by laser heating of N2O and N2O4 under high pressures in a diamond anvil cell. Synchrotron infrared absorption spectra of NONO3 2 were measured at pressures up to 32 GPa at room temperature. Raman spectra were obtained at pressures up to 40 GPa at room temperature and up to 14 GPa at temperatures down to 80 K. ...
متن کاملCharacterization of Developing Cotton Fibers by Confocal Raman Microscopy
Cellulose deposition in developing cotton fibers has been studied previously with analytical techniques, such as Fourier transform infrared spectroscopy (FTIR), High-performance liquid chromatography (HPLC) and Thermogravimetric analysis (TGA). Recent technological developments in instrumentation have made Raman microscopy emerge as an extraordinary analytical tool in biological and plant resea...
