, leading thus to an increase in the temperature. Simultaneously, the Raman spectra were recorded to monitor molecular changes from the AuNRs containing microenvironment. As depicted in Fig.2C, peak intensities at 750, 1000, 1207, and 1580 cm−1increased after exposure to the NIR laser. From...

Regulation of optical properties and electronic structure of graphitic carbon nitride (g-C3N4) via external strain has attracted much attention due to its potential in photocatalyst and electronic devices. However, the identification of g-C3N4 structure transformation induced by strain is greatly lacking...
In this work we show that the quality trend of the diamond-like/graphitic carbon ratio is critically dependent upon the boundary conditions of the analytic regions. We also examine the possibility of directly applying the peak height ratio HD/HG as an alternative method to analyze Raman spectra....
However, conflicting reports still exist on the diamond-like films analyzed by the fitting method of Raman spectra. In this work we show that the quality trend of the diamond-like/graphitic carbon ratio is critically dependent upon the boundary conditions of the analytic regions. We also examine...
Similarly, 1D CNT/PTFE-based FPNC has also been characterized by Raman spectroscopy, where change in the typical graphitic D and G bands of CNT was seen due to the impregnation with PTFE [27,83]. Sign in to download full-size image Figure 3.10. Raman spectra of (A) pristine PVDF (B)...
