摘要：Wurtzite CuGaS2 was successfully synthesized in a facile one-pot hydrothermal process using CuCl, Ga(NO3)(3) and thioacetamide as reagents. The as-prepared product was characterized with X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy and UV-vis spectroscopy. Furthermore, the application of CuGaS2 obtained in the trace detection of L-noradrenaline was explored as a photoluminescent probe. The results indicate that the as-preparedsample is an aggregation of wurtzite CuGaS2 nanosheets and nanorods, and possess high crystallinity. This CuGaS2 hierarchical nanostructure can exhibit a strong emission at 832 nm with full width at half maximum of approximate 20 nm. In addition, the as-prepared CuGaS2 possess high sensitivity to L-noradrenaline in water with a detectable concentration of 5.0 x 10(-7) mol L-1 when it used as a photoluminescent probe, implying that it is a promising candidate in the field of biological and chemical sensing in future.
