What Techniques are Used for Phase Identification?
Several techniques are employed to identify phases in nanomaterials:
X-ray Diffraction (XRD): This technique is widely used to determine the crystallographic structure and phase composition of nanomaterials. Transmission Electron Microscopy (TEM): TEM provides high-resolution images and diffraction patterns that can be used to identify phases and their distribution. Scanning Electron Microscopy (SEM): SEM combined with Energy Dispersive X-ray Spectroscopy (EDS) can provide information about the elemental composition and phases. Raman Spectroscopy: This technique is useful for identifying molecular phases and their vibrational modes. Fourier Transform Infrared Spectroscopy (FTIR): FTIR can identify different chemical phases based on their infrared absorption spectra.
