Findings from Nankai University in Nanomaterials Reported

June 3, 2014

By a News Reporter-Staff News Editor at Physics Week -- Current study results on Nanomaterials have been published. According to news reporting originating from Tianjin, People's Republic of China, by VerticalNews correspondents, research stated, "A simple approach for the synthesis of large quantities of CdS quantum dots doped silica nanomaterials was developed via sol-gel process at room temperature. 3-Mercaptopropyltrimethoxysilane was used as a cadmium chelator, and cadmium acetate as cadmium source and sodium sulphide as sulphur precursor during the preparation process. The effect of preparation conditions on properties of synthesized materials was discussed in detail."

Our news editors obtained a quote from the research from Nankai University, "The prepared CdS quantum dots doped silica particles were characterized using techniques such as scanning electron microscope (SEM), fluorescence spectroscopy, and UV-VIS absorption spectroscopy, respectively. The absorption peak is shifted towards shorter wavelengths compared with the bulk CdS."

According to the news editors, the research concluded: "The synthesized quantum dots doped silica nanoparticles exhibited strong emission."
