One-pot Synthesis of CdS Nanoparticles by Using $Cd(SOCCH_3)_2Lut_2$ Precusor and Their Optical Characteristics

$Cd(SOCCH_3)_2Lut_2$를 이용한 CdS 나노입자의 용이한 합성 방법 및 광학적 특성

A synthetic route for 12 metal thiocarboxylate complex, $Cd(SOCCH_3)_2Lut_2$ [Lut = 3,5-dimethylpyridine (lutidine)], were investigated for their potential to act as precursors for the formation of cadmium sulfide nanoparticles. $Cd(SOCCH_3)_2Lut_2$ were characterized by 1H-NMR spectroscopy. Thermal decomposition of $Cd(SOCCH_3)_2Lut_2$ is expected to undergo thiocarboxylic anhydride elimination to give stoichiometric cadmium sulfide nanoparticles and removes the organic supporting ligands cleanly. Prepared cadmium sulfide nanoparticles were characterized by fluorescence and UV-vis absorption spectroscopy and displayed an emission band at 500 nm with an excitation wavelength of 360 nm.
