title: Modified Eu-doped Y2 O3 nanoparticles as turn-off luminescent probes for the sensitive detection of pyridoxine.
abstract: Europium-doped yttrium oxide nanoparticles (Y2 O3 :Eu NPs) modified by captopril were prepared in aqueous solution. In this study, we report the effect of pyridoxine hydrochloride on the photoluminescence intensity of Y2 O3 :Eu NPs in pH 7.2 buffer solution. By increasing the pyridoxine concentration, the luminescence intensity of Y2 O3 :Eu NPs is quenched. The results show that this method demonstrates high sensitivity for pyridoxine determination. A linear relationship is observed between 0.0 and 62.0 μM with a correlation coefficient of 0.995 and a detection limit of 0.023 μM.
