A Near-Infrared Luminescent 11-Metal Cd(II)-Nd(III) Nanocluster for the Rapid Excitation Wavelength-Dependent Detection of Rutin

A near-infrared luminescent Cd-(II)-Nd-(III) nanocluster 1 (molecular dimensions of 1.0 nm x 2.2 nm x 2.2nm) was obtained using a Schiff base ligand. It can be used as a sensorfor the wavelength-dependent detection of rutin even in the presenceof other interference, which can be expressed by the third-order equation I (Ex470 nm)/I (Ex395 nm) = A[Rut](3) + B[Rut](2) + C[Rut] + D. 1 is used to analyze the Rut concentrations quantitatively in CH3CN and fetal calf serum (FCS). For the determination of Rutconcentrations in FCS, the ranges of recovery and relative standarddeviations are 99.06-104.70% and 2.30-4.15%, respectively. An 11-metal Cd-(II)-Nd-(III) nanocluster(moleculardimensions of 1.0 nm x 2.2 nm x 2.2 nm) was constructedfor the rapid excitation wavelength-dependent luminescence detectionof rutin.
