Abstract
We report the fabrication and fluorescent properties of hybrid material composed of fluorescent silica nanoparticles (FSNs) functionalized multi-walled carbon nanotubes(MWCNTs). Stöber method derived FSNs were successfully conjugated with MWCNTS chemically activated concentrated acids, poly(acrylic acid) (PAA) and 3-aminopropyl-trimethoxysilane (APTES) to obtain the nanocomposite FSNs/MWCNTs. Electron microscopic investigations revealed the spherical shape and smooth surface of FSNs with the diameter ~150±50 nm. Activated functional groups of MWCNTs provided the necessary support for functionalization of FSNs. FT-IR spectral analysis shows the structural integrity of FSNs, MWCNTs, and the hybrid FSNs/MWCNTs. Fluorescent emission property of FSNs/MWCNTs are observed to be significant than pristine dye fluorescein isothiocyanate and FSNs. Enhanced fluorescent emission and photostability of FSNs/MWCNTs provides promising feasibility for further exploration in biomedical applications.
