Raman etching
Webbför 2 dagar sedan · A confocal Raman microscopy system (Tokyo Instruments, Nanofinder 30, Tokyo, Japan) was used to perform Raman spectra and SERS analyses. The excitation was carried out by a He–Ne laser, and the laser power used was 0.1 mW for as–grown samples and 0.3 mW for the reference substrate.
