•Electron transfer from excited state of benzimidazole to alumina is not possible.•Energy transfer from the organic molecule to the alumina lattice.•Benzimidazole is adsorbed on the surface of alumina nanoparticles.
A new kind of fluorophore 2-(4-fluorophenyl)-1-phenyl-1H-benzo[d]imidazole (FPPBI) has been synthesized and characterized by 1H NMR, 13C NMR, mass spectral studies and single crystal XRD. The energy transfer from FPPBI to Al2O3 nanocrystals has been studied by absorption, fluorescence and lifetime spectroscopic methods. The association between nanoparticles and FPPBI is explained from both absorption and fluorescence quenching data. The distance between FPPBI and Al2O3 as well as the critical energy transfer distance has been deduced.
