We describe the development of a combined confocal and scanning near-field Raman microscope for operation at deep UV wavelengths. This instrument is based upon a commercially available Raman microscope and enables far-field and near-field Raman spect

The bonding in a series of unhydrogenated amorphous carbon films has been analyzed quantitatively using Raman spectroscopy excited by laser light in both the visible and ultraviolet regions of the spectrum. The asymmetry of the peak near 1550 cm−1

It is shown that Raman spectroscopy using UV excitation at 244 nm directly reveals the vibrational modes of sp 3 sites in tetrahedral amorphous carbon (ta-C). The spectrum of ta-C consists of two bands around 1100 cm −1 and 1600 cm −1 , which app

The photoluminescence and Raman spectra of several Ga1−xAlxN layers (0 ≤ x ≤ 0.86) grown on sapphire substrates by metal-organic vapor phase epitaxy have been recorded at room temperature, under an excitation at 244 nm. Using the photoluminesce

A range of explosives and narcotics have been examined using Raman spectroscopy with 244 nm excitation. This wavelength of excitation eliminates the fluorescence problems associated with excitation at visible wavelengths. Comparison with spectra obta

The bonding in a series of unhydrogenated amorphous carbon films has been analysed quantitatively using Raman spectroscopy with ultraviolet excitation. The Raman spectra exhibit two broad Raman peaks at 1650 cm−1 and 1100 cm−1, due to sp2 and sp3
