Experimental and theoretical investigation of spontaneous and surface-enhanced Raman scattering (SERS) spectroscopy of pure and boron-doped carbon nanotubes

In this paper,due to the importance and abundant applications of carbon nanotubes doped with boron (cnt/b2o3) in various industries with changes in the electrical,mechanical and chemical properties,mode identification and intensity of the raman spectra of pure and boron oxide molecule-doped spectra have been performed. the main task in this paper is to monitor the alteration of the relevant vibrational mode intensities of the pure and b-doped samples. in experimental approach,by utilizing a simple method we synthesized cnt doped with b2o3 using laser ablation in liquid environment technique. the silver nanoparticles were made by the lee–meisel method,and then the spontaneous and surface-enhanced raman scattering (sers) spectra of pure and b-doped carbon nanotubes were collected. in simulation approach,using the gauss view and gaussian software [basis set 6-31g,computational method dft (b3lyp)],the spontaneous and sers spectroscopy of pure and b-doped carbon nanotubes was calculated. due to the presence of silver nanoparticles in the vicinity of carbon nanotube and boron element,sers intensity to spontaneous raman (nr) intensity ratio (isers/inr) increases in the d,g and boron oxide modes of up to 12-fold were observed. a good agreement is found between the computational and the experimental sers results for the vibrational spectra of the synthesized composite materials. © 2018,the author(s).
