Abstract:
Local environment dependent photoluminescence (PL) of cerium incorporated GO nanoparticles (GO−Ce NPs) is investigated by using fluorescence quenching study in presence of aromatic nitro compounds (ANCs) and fluoride ion. Presence of trivalent and tetravalent cerium ions at the different locations of the GO based nanoparticles interact with ANCs and fluoride ions in a different manner depending upon the accessibility and local polarity of the excited cerium (III) ions. Proposed system is found to be most sensitive towards ortho‐nitrophenol (quenching efficiency 70.5 %) with a high constant value of K D and K S , 8.7 × 10 4 and 7.0 × 10 4 respectively. Herein, the fluorescence quenching study of GO−Ce NP S reveals the different mode of interactions between the fluorophoric moieties and quenchers.
