Raman spectroscopic studies of CuFeO2 at high pressures

Structural stability of a multiferroic compound CuFeO2 belonging to the delafossite family has been investigated at high pressures using in-situ Raman spectroscopy. At ambient conditions, CuFeO2 has a rhombohedral structure with space group R3m. It has two Raman active modes, identified as Eg and A1g. Both Raman mode frequencies harden with pressure. At 18 GPa, the doubly degenerate mode Eg spl...

Raman Spectroscopic Studies of Bioactive Materials

Bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. In this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. The structure and bioactivity of these samples based on their interaction with simulated body fluid (SBF) have been determined. In-vitor, using the Raman s...

Raman Spectroscopic Studies of Polyfluorenes

Polyfluorenes reveal a complex interplay between emissive properties and intraand intermolecular structure. Vibrational frequencies and intensities determined by Raman spectroscopy are strongly influenced by variations in the backbone as well as side chain conformations. Changes in the structural and electronic properties of two side group substituted polyfluorenes (PF): ethyl-hexyl substituted...
