By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Quantum Dots are presented in a new report. According to news reporting from Hubei, People's Republic of China, by NewsRx journalists, research stated, "A novel two-step controlled basic water phase method has been developed for synthesizing size-tunable and water-soluble CdTe/Cd(OH)(2) core/shell quantum dots with high quantum yield and good stability. The size of the prepared CdTe/Cd(OH)(2) core/shell quantum dots can be easily manipulated by varying the concentrations of NaOH solution step by step."
The news correspondents obtained a quote from the research from Huazhong Agricultural University, "The maximal emission wavelengths of the series CdTe/Cd (OH)(2) core/shell QDs were from 513 nm to 610 nm (emission colors tuned from green to red). The CdTe/Cd(OH)(2) core/shell quantum dots not only possess high quantum yield (up to 83%) but also exhibit excellent photostability (being stable after being stored for more than 2 months). The CdTe/Cd(OH)(2) core/shell quantum dots were characterized by transmission electron microscopy, high-resolution transmission electron microscopy, X-ray powder diffraction spectrometry, ultraviolet visible spectrometry and fluorescence spectrometry. The water-soluble nature of the CdTe/Cd(OH)(2) core/shell quantum dots offers great potentiality for their chemical and biological applications. This method is easily controlled, low-cost and reproducible."
According to the news reporters, the research concluded: "So it is possible to extend this approach to the preparation of other size-tunable inorganic metal hydroxide capped core/shell quantum dots."
